Abstract
Description
Technical Field
[0001] This invention relates to a vibration isolation device design auxiliary device, a vibration isolation device design auxiliary program, and a vibration isolation device design auxiliary method.
[0002] This application claims priority based on Japanese Patent Application No. 2019-110592 and Japanese Patent Application No. 2019-110594, both filed in Japan on June 13, 2019, the contents of which are incorporated herein by reference. Background Technology
[0003] When determining the specifications of components used in vehicles sold on the market, automakers or auto parts manufacturers sometimes conduct the following tests: they create prototype parts and assemble them in a real vehicle to collect various data by actually running the vehicle.
[0004] Furthermore, such testing requires labor to manufacture prototype parts and to make the actual vehicle run. Therefore, for example, the spring design system disclosed in Patent Document 1 can be used to reduce such labor.
[0005] The spring design system disclosed in Patent Document 1 includes a spring calculation unit, a spring characteristic database, and a server. The spring calculation unit performs spring calculations on the helical spring based on the specification data and outputs specification data containing the characteristic values of the helical spring as a result. The spring characteristic database determines whether the specification data containing the obtained characteristic values of the helical spring is suitable for the required specifications. The server determines whether the specification data is suitable as data for the helical spring based on the calculation results and the determination data, and outputs the determination result.

[0009] However, when the specifications for the coil springs used in the spring calculations are insufficient, the aforementioned spring design system sometimes determines that coil springs that do not meet the expected results in the aforementioned tests are suitable as coil springs. In other words, the aforementioned spring design system sometimes determines that coil springs that should not be used are suitable. In addition, components such as vibration isolation devices used to suppress vibrations of automobile components have more complex structures than coil springs, and therefore may be more prone to misjudgments due to insufficient specifications.
[0010] On the other hand, automakers or auto parts manufacturers sometimes use simulations to collect the aforementioned data in order to save the labor required for actual vehicle testing. However, even when simulations are used, insufficient specification data can make misjudgments more likely to occur. Summary of the Invention

[0034] [First Implementation Method]
[0035] Reference Figures 1 to 4 An example of a vibration isolation device design aid device according to the first embodiment of the present invention will be described. Figure 1 This is a diagram illustrating an example of an auxiliary device for designing a vibration isolation device according to the first embodiment of the present invention. Figure 1 As shown, the vibration isolation device design auxiliary device 11 includes an adjustment unit 111, an acquisition unit 112, a determination unit 113, and a proposal unit 114.
[0036] The adjustment unit 111 adjusts the response characteristics of the motion element included in the first vibration isolation device used to attenuate the vibration of components constituting the actual vehicle. The first vibration isolation device is, for example, a liquid-sealed bushing, assembled into the actual vehicle used in the actual vehicle test. The motion element is an element that is fixed in motion by components or combinations of these components constituting the first vibration isolation device. Furthermore, the motion element includes a liquid sealed within the first vibration isolation device. The response characteristic is the characteristic of the motion element's response to vibration input to the motion element. Furthermore, the response characteristic is not necessarily limited to one type; sometimes it includes multiple characteristics such as amplitude dependence, attenuation characteristics, velocity dependence, and frequency characteristics of the motion element. Here, the data representing the response characteristics adjusted by the adjustment unit 111 is referred to as response characteristic data.
[0037] Figure 2 This is a diagram illustrating an example of the response characteristics after adjustment by the vibration isolation device design assistance device according to the first embodiment of the present invention. For example, the adjustment unit 111 is as follows: Figure 2 As shown, a setting value "a111" is set for the response characteristic A11 of the specified operating element of the first vibration isolation device. The setting value referred to here is the value that determines the response characteristic A11. In addition, the adjustment unit 111 sets a setting value "a112" for the response characteristic A12 of the operating element of the first vibration isolation device, and sets a setting value "a113" for the response characteristic A13 of the operating element of the first vibration isolation device.
[0038] Specifically, the adjustment unit 111 sets these setting values by adjusting the position of the components constituting the first vibration isolation device or the shape or cross-sectional area of the flow path of the liquid sealed in the first vibration isolation device using a servo mechanism or actuator. Furthermore, when the liquid sealed in the first vibration isolation device is an electroviscous fluid, the adjustment unit 111 adjusts the viscosity by applying voltage to the liquid using electrodes, thereby setting these setting values.
[0039] Furthermore, the adjustment unit 111 can also replace setting a single setting value that determines the response characteristics of the operating elements of the first vibration isolation device, or set a range of setting values that determine the response characteristics, or conditions expressed numerically, etc.
[0040] The acquisition unit 112 acquires vibration data and response data. The vibration data represents the vibration data input to the motion element when using a real vehicle equipped with the first vibration isolation device, for example, during a real vehicle test using that vehicle. The vibration data includes, for example, data representing displacement, velocity, acceleration, and the load causing the vibration. The response data represents the response of the motion element to the vibration shown by the vibration data. The response data includes, for example, data representing displacement, velocity, and acceleration of the motion element.
[0041] Figure 3This is a diagram illustrating an example of vibration data acquired by the vibration isolation device design aid according to the first embodiment of the present invention. For example, such as... Figure 3 As shown, when vibration B11 is input to a predetermined operating element of the first vibration isolation device during a real vehicle test, the acquisition unit 112 acquires vibration data representing the value "b111" describing vibration B11. Similarly, as Figure 3 As shown, when vibration B12 is input to a predetermined operating element of the first vibration isolation device, the acquisition unit 112 acquires vibration data representing the value "b112" describing vibration B12, and when vibration B13 is input to a predetermined operating element of the first vibration isolation device, the acquisition unit 112 acquires vibration data representing the value "b113" describing vibration B13.
[0042] Furthermore, the acquisition unit 112 may acquire multiple values instead of acquiring one value describing the vibration shown by the vibration data, or acquire a range of values describing the vibration, a formula describing the vibration, etc.
[0043] Figure 4 This diagram illustrates an example of response data acquired by the vibration isolation device design assistance device according to the first embodiment of the present invention. For example, the specified operating elements of the first vibration isolation device in a real vehicle test are... Figure 3 The vibration B11 shown corresponds to the response C11, and the acquisition unit 112 acquires response data representing the value "c111" describing the response C11. Similarly, in the actual vehicle test, the specified operating elements of the first vibration isolation device are... Figure 3 The vibration B12 shown corresponds to the response C12, and the acquisition unit 112 acquires response data representing the value "c112" describing the response C12. Furthermore, in the actual vehicle test, the specified operating elements of the first vibration isolation device are... Figure 3 The vibration B13 shown corresponds to the response C13, and the acquisition unit 112 acquires response data representing the value "c113" describing the response C13.
[0044] Furthermore, the acquisition unit 112 may acquire multiple values instead of acquiring one value describing the response shown by the response data, or acquire a range of values describing the response, a formula describing the response, etc.
[0045] The determination unit 113 determines whether the response shown by the response data meets the target response. The target response is the condition that the response data of the action element of the vibration isolation device, i.e., the second vibration isolation device, assembled into a real vehicle sold on the market, needs to meet, and is determined by the specifications of the real vehicle, etc.
[0046] The proposal unit 114 performs necessary determinations in order to propose a second vibration isolation device. For example, the proposal unit 114 determines whether a second vibration isolation device exists that can produce the response shown by the response data acquired by the acquisition unit 112. Specifically, the proposal unit 114 determines whether such a second vibration isolation device is listed in a catalog. Furthermore, if the proposal unit 114 determines that a second vibration isolation device that can produce the response shown by the response data acquired by the acquisition unit 112 does not exist, the proposal unit 114 determines whether it is possible to manufacture a second vibration isolation device that can produce the response shown by the response data acquired by the acquisition unit 112.
[0047] Furthermore, if the proposal unit 114 determines that there is a second vibration isolation device capable of performing the response shown by the response data obtained by the acquisition unit 112, it proposes a second vibration isolation device based on at least one of the response characteristic data, vibration data, and response data.
[0048] Figure 5 This is a diagram illustrating an example of the response characteristics, vibration, and response of each of the plurality of second vibration isolation devices according to the first embodiment of the present invention. Figure 5 Vibration isolation devices D11, D12, and D13, as shown, are listed in, for example, a catalog of vibration isolation devices. The response characteristic A11 of vibration isolation device D11 is determined by the set value "a111", the response characteristic A12 is determined by the set value "a112", and the response characteristic A13 is determined by the set value "a113". Furthermore, when vibration B11, described by vibration data "b111", is input to the motion element, vibration isolation device D11 displays a response C11, described by response data "c111". Similarly, when vibration B12, described by vibration data "b112", is input to the motion element, vibration isolation device D11 displays a response C12, described by response data "c112", and when vibration B13, described by vibration data "b113", is input to the motion element, it displays a response C13, described by response data "c113". Additionally, these cases are... Figure 5 The vibration isolation devices D12 and D13 shown are the same.
[0049] Specifically, in Figure 3 The vibration B11 described by the vibration data "b111" shown is input to the first vibration isolation device, and the operating elements of the first vibration isolation device are shown. Figure 4 In the case of response C11 described by the response data "c111", the proposal unit 114 proposes a vibration isolation device D11 exhibiting the same behavior. That is, the proposal unit 114 proposes a second vibration isolation device that is identical to the first vibration isolation device. Similarly, in Figure 3 The vibration B12 described by the vibration data "b112" shown is input to the first vibration isolation device, and the operating elements of the first vibration isolation device are shown. Figure 4 In the case of response C12 described by the response data "c112", proposal 114 proposes a vibration isolation device D11 that exhibits the same behavior. Additionally, in Figure 3 The vibration B13 described by the vibration data "b113" shown is input to the first vibration isolation device, and the operating elements of the first vibration isolation device are shown. Figure 4 In the case of response C13, described by response data "c113", proposal 114 proposes a vibration isolation device D11 exhibiting the same behavior. Furthermore, these cases are for... Figure 5 The vibration isolation devices D12 and D13 shown are the same.
[0050] Or, in Figure 3 The vibration B11 described by the vibration data "b111" shown is input to the first vibration isolation device, and the operating elements of the first vibration isolation device are shown. Figure 4 In the case of response C11 described by the response data "c111", proposal unit 114 proposes a vibration isolation device D12 that exhibits behavior close to that behavior. That is, proposal unit 114 proposes a second vibration isolation device having response characteristics relatively close to the first vibration isolation device. In this case, Figure 5 The vibration isolation device D12 shown has a set value "a121" representing the response characteristic A11, a value "b121" describing the vibration B11, and a value "c121" describing the response C11, which are respectively within the specified range and Figure 2 The set value "a111" shown is Figure 3 The value "b111" shown and Figure 4 The value shown, "c111", is close to the value. Additionally, this situation applies to... Figure 5 The other values shown are the same.
[0051] Alternatively, if the proposal unit 114 determines that it is possible to manufacture a second vibration isolation device capable of producing the response shown by the response data acquired by the acquisition unit 112, it proposes a second vibration isolation device designed based on at least one of the response characteristic data, vibration data, and response data. Specifically, the proposal unit 114 proposes a second vibration isolation device that is not listed in a catalog or the like, based on the response characteristic data representing the response characteristics adjusted by the adjustment unit 111 and the vibration data and response data acquired by the acquisition unit 112.
[0052] Furthermore, there are no particular limitations on the manner in which the proposal department 114 proposes the second vibration isolation device. For example, the proposal department 114 may propose the second vibration isolation device by displaying the response characteristic data, vibration data, response data, etc. of the proposed second vibration isolation device on a display screen.
[0053] Next, refer to Figure 6This is an example of the processing performed by the vibration isolation device design auxiliary device 11. Figure 6 This is a flowchart illustrating an example of the processing performed by the vibration isolation device design assistance device according to the first embodiment of the present invention.
[0054] In step S111, the adjustment unit 111 adjusts the response characteristics of the motion elements included in the first vibration isolation device.
[0055] In step S112, a real vehicle test is conducted, and the acquisition unit 112 acquires vibration data and response data.
[0056] In step S113, the determination unit 113 determines whether the response shown by the response data obtained in step S112 satisfies the target response.
[0057] In step S114, the adjustment unit 111 adjusts the response characteristics of the motion elements included in the first vibration isolation device, so that the processing returns to step S112.
[0058] In step S115, the proposal unit 114 determines whether a second vibration isolation device exists that can produce the response shown by the response data obtained in step S112. If the proposal unit 114 determines that a second vibration isolation device exists that can produce the response shown by the response data obtained in step S112 (step S115: "Yes"), the process proceeds to step S116. On the other hand, if the proposal unit 114 determines that a second vibration isolation device does not exist that can produce the response shown by the response data obtained in step S112 (step S115: "No"), the process proceeds to step S117.
[0059] In step S116, the proposal unit 114 proposes a second vibration isolation device with pre-designed response characteristics based on at least one of the response characteristic data, vibration data, and response data, and then ends the process.
[0060] In step S117, the proposal unit 114 determines whether a second vibration isolation device capable of producing the response shown by the response data obtained in step S112 can be manufactured. If the proposal unit 114 determines that a second vibration isolation device capable of producing the response shown by the response data obtained in step S112 can be manufactured (step S117: "Yes"), the process proceeds to step S118. On the other hand, if the proposal unit 114 determines that a second vibration isolation device capable of producing the response shown by the response data obtained in step S112 cannot be manufactured (step S117: "No"), the process ends.
[0061] In step S118, the proposal unit 114 proposes a second vibration isolation device designed based on at least one of the response characteristic data, vibration data, and response data, and then ends the process.
[0062] The vibration isolation device design assistance device 11 according to the first embodiment of the present invention has been described above. The vibration isolation device design assistance device 11 adjusts the response characteristics of the operating elements included in a first vibration isolation device for attenuating the vibration of components constituting a vehicle, and acquires vibration data and response data. Then, the vibration isolation device design assistance device 11 proposes a second vibration isolation device based on at least one of the response characteristic data, vibration data, and response data representing the response characteristics adjusted by the adjustment unit 111. Thus, the vibration isolation device design assistance device 11 can effectively collect the data needed when determining the vibration isolation device used in a vehicle and propose a vibration isolation device that exhibits the desired response characteristics based on that data.
[0063] Furthermore, the vibration isolation device design aid 11 proposes a second vibration isolation device with pre-designed response characteristics. Specifically, the vibration isolation device design aid 11 proposes a second vibration isolation device listed in a catalog or the like based on at least one of response characteristic data, vibration data, and response data. Thus, the vibration isolation device design aid 11 can assist automobile manufacturers or automobile component manufacturers in quickly selecting a vibration isolation device that can achieve the desired response characteristics.
[0064] Furthermore, the vibration isolation device design aid 11 proposes a second vibration isolation device designed based on at least one of response characteristic data, vibration data, and response data. Specifically, the vibration isolation device design aid 11 proposes a second vibration isolation device that is not listed in catalogs or the like based on at least one of these data. Thus, even if a vibration isolation device that can achieve the desired response characteristics is not listed in catalogs or the like, or is not sold on the market, the vibration isolation device design aid 11 can still propose a specific vibration isolation device that can achieve the desired response characteristics.
[0065] Furthermore, the first embodiment described above illustrates a scenario where the first vibration isolation device is assembled into a real vehicle used in a real vehicle test, but this is not a limitation. For example, the first vibration isolation device could also be a vibration isolation device assembled into a real vehicle sold on the market.
[0066] Alternatively, the aforementioned proposal unit 114 can also be implemented by a device different from the device having the functions of the adjustment unit 111, the acquisition unit 112, and the determination unit 113. In this case, the proposal unit 114 can also represent the proposal... Figure 6 The data of the second vibration isolation device mentioned in step S116 or step S118 is sent to other devices to inform those other devices of the specific specifications of the second vibration isolation device. Furthermore, the other devices mentioned here can be the vibration isolation device design assistance device 11, or any other device.
[0067] in addition, Figure 1At least a portion of the functions of the vibration isolation device design aid 11 shown can also be implemented by executing a program using hardware including a circuit section. The hardware referred to here includes, for example, a CPU (Central Processing Unit), an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), a FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit). Furthermore, the aforementioned program can also be stored in... Figure 7 The computer-readable storage medium 120 shown herein. Examples of such storage media include HDD (Hard Disk Drive), flash memory, USB storage, ROM (Read Only Memory), and DVD (Digital Versatile Disc). Furthermore, the above program can also be implemented... Figure 1 The differential program is a part of the functions of the vibration isolation device design auxiliary device 11 shown.
[0068] The first embodiment of the present invention has been described above with reference to the accompanying drawings. However, the vibration isolation device design aid 11 is not limited to the first embodiment described above, and various modifications, substitutions, combinations, or design changes can be applied within the scope of the present invention as defined in the claims.
[0069] In addition, in the above-mentioned vibration isolation device design auxiliary device, the proposal department proposes a second vibration isolation device with pre-designed response characteristics.
[0070] In addition, in the above-mentioned vibration isolation device design assistance device, the proposal department proposes a second vibration isolation device designed based on at least one of the response characteristic data, the vibration data and the response data.
[0071] One aspect of the present invention is a vibration isolation device design aid program for enabling a computer to perform the following functions: an adjustment function for adjusting the response characteristics of a motion element included in a first vibration isolation device for attenuating vibrations of components constituting a vehicle; an acquisition function for acquiring vibration data and response data, wherein the vibration data represents vibrations input to the motion element when the vehicle equipped with the first vibration isolation device is used, and the response data represents the response of the motion element to the vibrations indicated by the vibration data; and a proposal function for proposing a second vibration isolation device based on at least one of response characteristic data representing the response characteristics adjusted by the adjustment function, the vibration data, and the response data.
[0072] One aspect of the present invention is a method for assisting in the design of a vibration isolation device, comprising the following steps: an adjustment step, adjusting the response characteristics of a motion element included in a first vibration isolation device for attenuating vibrations of components constituting a vehicle; an acquisition step, acquiring vibration data and response data, wherein the vibration data represents vibrations input to the motion element when the vehicle equipped with the first vibration isolation device is used, and the response data represents the response of the motion element to the vibrations indicated by the vibration data; and a proposal step, proposing a second vibration isolation device based on at least one of response characteristic data representing the adjusted response characteristics in the adjustment step, the vibration data, and the response data.
[0073] [Second Implementation]
[0074] Reference Figures 8 to 11 An example of a vibration isolation device design aid device according to the second embodiment of the present invention will be described. Figure 8 This is a diagram illustrating an example of an auxiliary device for designing a vibration isolation device according to a second embodiment of the present invention.
[0075] like Figure 8 As shown, the vibration isolation device design auxiliary device 21 includes an adjustment unit 211, an acquisition unit 212, a determination unit 213, and a proposal unit 214.
[0076] The adjustment unit 211 adjusts the response characteristics of the motion elements included in the virtual vibration isolation device used to dampen the vibrations of components constituting the simulated vehicle, i.e., the virtual vehicle. The virtual vibration isolation device, for example, is a virtual liquid-sealed bushing used in the simulation, assembled into the simulated vehicle. The motion element is an element that is fixed in motion by components or combinations of these components constituting the virtual vibration isolation device. Furthermore, the motion element includes a liquid sealed within the virtual vibration isolation device. The response characteristic is the characteristic of the motion element's response to vibrations input to the motion element. Furthermore, the response characteristic is not necessarily limited to one type; sometimes it includes multiple characteristics such as amplitude dependence, damping characteristics, velocity dependence, and frequency characteristics of the motion element. Here, the data representing the response characteristics adjusted by the adjustment unit 211 is referred to as response characteristic data.
[0077] Figure 9 This is a diagram illustrating an example of the response characteristics after adjustment by the vibration isolation device design aid according to the second embodiment of the present invention. For example, such as... Figure 9 As shown, the adjustment unit 211 sets a setting value "a211" for the response characteristic A21 of the specified operating elements of the virtual vibration isolation device. The setting value referred to here is the value that determines the response characteristic A21. In addition, the adjustment unit 211 sets a setting value "a212" for the response characteristic A22 of the operating elements of the virtual vibration isolation device, and sets a setting value "a213" for the response characteristic A23 of the operating elements of the virtual vibration isolation device.
[0078] Furthermore, the adjustment unit 211 can also set multiple setting values instead of setting a single setting value that determines the response characteristics of the virtual vibration isolation device's operating elements, or set a range of setting values that determine the response characteristics, or conditions expressed numerically. Additionally, the adjustment unit 211 preferably adjusts the response characteristics of the virtual vibration isolation device's operating elements within the range of the response characteristics that a vibration isolation device mounted on a real vehicle can exhibit.
[0079] The acquisition unit 212 acquires vibration data and response data. Vibration data represents the vibrations input to motion elements in a simulation relating to the use of a virtual vehicle equipped with a virtual vibration isolation device. Vibration data may include, for example, data representing displacement, velocity, acceleration, and the load causing the vibration. Response data represents the response of the motion element to the vibrations shown by the vibration data. Response data may include, for example, data representing displacement, velocity, and acceleration of the motion element.
[0080] Figure 10 This is a diagram illustrating an example of vibration data acquired by the vibration isolation device design aid according to the second embodiment of the present invention. For example, such as... Figure 10As shown, in a simulation related to the use of a virtual vehicle, when vibration B21 is input to a specified action element of the virtual vibration isolation device, the acquisition unit 212 acquires vibration data representing the value "b211" describing vibration B21. Similarly, as Figure 10 As shown, when vibration B22 is input to the prescribed operating elements of the virtual vibration isolation device, the acquisition unit 212 acquires vibration data representing the value "b212" describing vibration B22. When vibration B23 is input to the prescribed operating elements of the virtual vibration isolation device, the acquisition unit 212 acquires vibration data representing the value "b213" describing vibration B23.
[0081] Furthermore, the acquisition unit 212 may acquire multiple values instead of acquiring one value describing the vibration shown by the vibration data, or acquire a range of values describing the vibration, a formula describing the vibration, etc.
[0082] Figure 11 This diagram illustrates an example of response data acquired by the vibration isolation device design assistance device according to the second embodiment of the present invention. For example, in a simulation related to the use of a virtual vehicle, the specified operating elements of the virtual vibration isolation device are... Figure 10 When vibration B21 is shown, correspondingly indicating response C21, acquisition unit 212 acquires response data representing the value "c211" describing response C21.

Figure 10 When vibration B22 is shown, correspondingly indicating response C22, acquisition unit 212 acquires response data representing the value "c212" describing response C22. Furthermore, in simulations related to the use of virtual vehicles, the prescribed operating elements of the virtual vibration isolation device are... Figure 10 The vibration B23 shown corresponds to the response C23, and response data representing the value "c213" describing the response C23 is obtained.
[0083] Furthermore, the acquisition unit 212 may acquire multiple values instead of acquiring one value describing the response shown by the response data, or acquire a range of values describing the response, a formula describing the response, etc.
[0084] The determination unit 213 determines whether the response shown by the response data meets the target response. The target response is a condition that the response data of the vibration isolation device, which is a vibration isolation device assembled into a real vehicle sold on the market, needs to meet, and is determined by the specifications of the real vehicle, etc.
[0085] The proposal unit 214 performs necessary determinations in order to propose a vibration isolation device. For example, the proposal unit 214 determines whether a vibration isolation device exists that can produce the response shown by the response data acquired by the acquisition unit 212. Specifically, the proposal unit 214 determines whether such a vibration isolation device is listed in a catalog. Furthermore, if the proposal unit 214 determines that a vibration isolation device that can produce the response shown by the response data acquired by the acquisition unit 212 does not exist, the proposal unit 214 determines whether a vibration isolation device that can produce the response shown by the response data acquired by the acquisition unit 212 can be manufactured.
[0086] Furthermore, if the proposal department 214 determines that there is a vibration isolation device capable of performing the response shown by the response data obtained by the acquisition department 212, it proposes a vibration isolation device to be mounted on the actual vehicle based on at least one of the response characteristic data, vibration data, and response data.
[0087] Figure 12 This is a diagram illustrating an example of the response characteristics, vibration, and response of each of the plurality of vibration isolation devices according to the second embodiment of the present invention. Figure 12 Vibration isolation devices D21, D22, and D23, as shown, are listed in, for example, a catalog of vibration isolation devices. The response characteristic A21 of vibration isolation device D21 is determined by the set value "a211", the response characteristic A22 by the set value "a212", and the response characteristic A23 by the set value "a213". Furthermore, when vibration B21, described by vibration data "b211", is input to the motion element, vibration isolation device D21 displays the response C21, described by response data "c211". Similarly, when vibration B22, described by vibration data "b212", is input to the motion element, vibration isolation device D21 displays the response C22, described by response data "c212", and when vibration B23, described by vibration data "b213", is input to the motion element, it displays the response C23, described by response data "c213". Additionally, these conditions apply to… Figure 12 The vibration isolation devices D22 and D23 shown are the same.
[0088] Specifically, in Figure 10 The vibration B21 described by the vibration data "b211" shown is input to the virtual vibration isolation device, and the motion elements of the virtual vibration isolation device are shown. Figure 11 In the case of response C21 described by the response data "c211", proposal unit 214 proposes a vibration isolation device D21 exhibiting the same behavior. That is, proposal unit 214 proposes a vibration isolation device identical to the virtual vibration isolation device. Similarly, in Figure 10 The vibration B22 described by the vibration data "b212" shown is input into the virtual vibration isolation device, and the motion elements of the virtual vibration isolation device are shown. Figure 11In the case of response C22 described by response data "c212", proposal 214 proposes a vibration isolation device D21 that exhibits the same behavior. Additionally, in Figure 10 The vibration B23 described by vibration data "b213" is shown and input into the virtual vibration isolation device. The motion elements of the virtual vibration isolation device are shown. Figure 11 In the case of response C23 described by response data "c213", proposal 214 proposes a vibration isolation device D21 exhibiting the same behavior. Furthermore, these cases are for... Figure 12 The vibration isolation devices D22 and D23 shown are the same.
[0089] Or, in Figure 10 The vibration B21 described by the vibration data "b211" shown is input to the virtual vibration isolation device, and the motion elements of the virtual vibration isolation device are shown. Figure 11 In the case of response C21 described by the response data "c211", proposal unit 214 proposes a vibration isolation device D22 that exhibits behavior close to that behavior. That is, proposal unit 214 proposes a vibration isolation device having response characteristics that are relatively close to the virtual vibration isolation device. In this case, Figure 12 The vibration isolation device D22 shown has a set value "a221" representing the response characteristic A21, a value "b221" describing the vibration B21, and a value "c221" describing the response C21, which are respectively within the specified range and Figure 9 The set value "a211" shown is Figure 10 The value "b211" shown is as follows Figure 11 The value shown, "c211", is close to the value. Additionally, this situation applies to... Figure 12 The other values shown are the same.
[0090] Alternatively, if the proposal unit 214 determines that it is possible to manufacture a vibration isolation device capable of producing the response shown by the response data acquired by the acquisition unit 212, it proposes a vibration isolation device designed based on at least one of the response characteristic data, vibration data, and response data. Specifically, the proposal unit 214 proposes a vibration isolation device not listed in catalogs or the like based on the response characteristic data representing the response characteristics adjusted by the adjustment unit 211, and the vibration data and response data acquired by the acquisition unit 212.
[0091] Furthermore, the method by which the proposal department 214 proposes a vibration isolation device is not particularly limited. For example, the proposal department 214 may propose a vibration isolation device by displaying the response characteristic data, vibration data, response data, etc. of the proposed vibration isolation device on a display screen.
[0092] Next, refer to Figure 13 This is an example of the processing performed by the vibration isolation device design auxiliary device 21. Figure 13This is a flowchart illustrating an example of the processing performed by the vibration isolation device design assistance device according to the second embodiment of the present invention.
[0093] In step S211, the adjustment unit 211 adjusts the response characteristics of the motion elements included in the virtual vibration isolation device.
[0094] In step S212, a simulation related to the use of a virtual vehicle equipped with a virtual vibration isolation device is performed, and the acquisition unit 212 acquires vibration data and response data.
[0095] In step S213, the determination unit 213 determines whether the response shown by the response data obtained in step S212 satisfies the target response.
[0096] In step S214, the adjustment unit 211 adjusts the response characteristics of the motion elements contained in the virtual vibration isolation device, so that the processing returns to step S212.
[0097] In step S215, the proposal unit 214 determines whether a vibration isolation device exists that can produce the response shown by the response data obtained in step S212. If the proposal unit 214 determines that a vibration isolation device exists that can produce the response shown by the response data obtained in step S212 (step S215: "Yes"), the process proceeds to step S216. On the other hand, if the proposal unit 214 determines that a vibration isolation device does not exist that can produce the response shown by the response data obtained in step S212 (step S215: "No"), the process proceeds to step S217.
[0098] In step S216, the proposal unit 214 proposes a vibration isolation device with pre-designed response characteristics based on at least one of the response characteristic data, vibration data, and response data, and then ends the process.
[0099] In step S217, the proposal unit 214 determines whether it is possible to manufacture a vibration isolation device capable of producing the response shown by the response data obtained in step S212. If the proposal unit 214 determines that it is possible to manufacture a vibration isolation device capable of producing the response shown by the response data obtained in step S212 (step S217: "Yes"), the process proceeds to step S218. On the other hand, if the proposal unit 214 determines that it is impossible to manufacture a vibration isolation device capable of producing the response shown by the response data obtained in step S212 (step S217: "No"), the process ends.
[0100] In step S218, the proposal unit 214 proposes a vibration isolation device designed based on at least one of the response characteristic data, vibration data, and response data, and then ends the process.
[0101] The vibration isolation device design assistance device 21 according to the second embodiment of the present invention has been described above. The vibration isolation device design assistance device 21 adjusts the response characteristics of the motion elements included in a virtual vibration isolation device used to attenuate the vibration of components constituting a simulated vehicle, i.e., a virtual vehicle, and acquires vibration data and response data. Then, the vibration isolation device design assistance device 21 proposes a vibration isolation device based on at least one of the response characteristic data, vibration data, and response data representing the response characteristics adjusted by the adjustment unit 211. Thus, it is possible to effectively collect the data needed to determine the vibration isolation device used in a vehicle through simulation and propose a vibration isolation device that exhibits the desired response characteristics based on that data.
[0102] Furthermore, the vibration isolation device design aid 21 proposes vibration isolation devices with pre-designed response characteristics. Specifically, the vibration isolation device design aid 21 proposes vibration isolation devices listed in catalogs, etc., based on at least one of response characteristic data, vibration data, and response data. Thus, the vibration isolation device design aid 21 can assist automobile manufacturers or automobile component manufacturers in quickly selecting vibration isolation devices that can achieve the desired response characteristics.
[0103] Furthermore, the vibration isolation device design aid 21 proposes a vibration isolation device designed based on at least one of response characteristic data, vibration data, and response data. Specifically, the vibration isolation device design aid 21 proposes a vibration isolation device that is not listed in catalogs or the like based on at least one of these data. Thus, even if a vibration isolation device that can achieve the desired response characteristics is not listed in catalogs or the like or is not sold on the market, the vibration isolation device design aid 21 can still propose a specific vibration isolation device that can achieve the desired response characteristics.
[0104] Furthermore, the vibration isolation device design aid 21 adjusts the response characteristics of the virtual vibration isolation device's motion elements within the range of response characteristics that a vibration isolation device mounted on a real vehicle can exhibit. Thus, the vibration isolation device design aid 21 can perform realistic simulations and propose vibration isolation devices that are actually listed in the catalog and can be actually manufactured.
[0105] Furthermore, the aforementioned proposal unit 214 can also be implemented by a device different from the device having the functions of the adjustment unit 211, the acquisition unit 212, and the determination unit 213. In this case, the proposal unit 214 can also represent the proposal... Figure 13 The data of the second vibration isolation device mentioned in step S216 or step S218 is transmitted to other devices via a network to inform those other devices of the specific specifications of the second vibration isolation device. Furthermore, the other devices mentioned here can be the vibration isolation device design assistance device 21, or any other device.
[0106] in addition, Figure 8 At least a portion of the functions of the vibration isolation device design aid 21 shown can also be implemented by executing a program using hardware including a circuit section. The hardware referred to here includes, for example, a CPU (Central Processing Unit), LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit). Furthermore, the aforementioned program can also be stored in... Figure 14 The computer-readable storage medium 220 shown herein. Examples of such storage media include HDD (Hard Disk Drive), flash memory, USB storage, ROM (Read Only Memory), and DVD (Digital Versatile Disc). Furthermore, the above program can also be implemented... Figure 8 The differential program is a part of the functions of the vibration isolation device design auxiliary device 21 shown.
[0107] The second embodiment of the present invention has been described above with reference to the accompanying drawings. However, the vibration isolation device design aid 21 is not limited to the second embodiment described above, and various modifications, substitutions, combinations, or design changes can be applied without departing from the spirit of the present invention.
[0108] Furthermore, in the aforementioned vibration isolation device design auxiliary device, the proposal department proposes a vibration isolation device with pre-designed response characteristics.
[0109] Furthermore, in the aforementioned vibration isolation device design assistance device, the proposal department proposes a vibration isolation device designed based on at least one of the response characteristic data, the vibration data, and the response data.
