[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0026] In the present invention, Figure 1 and Figure 2The vibration absorber combination structure shown in the figure comprises a main body bracket 1, a movable bracket 2 and an adjustment component 3; the movable bracket 2 is detachably mounted on the main body bracket 1; the adjustment component 3 comprises a main body mass block 31, a detachable rubber plug 32, at least one movable mass block 33 and two sleeves 34; the movable mass block 33 is detachably mounted on the main body mass block 31; the two sleeves 34 are respectively sleeved on the two ends of the main body mass block 31; each end of the sleeve 34 away from the main body mass block 31 is mounted on the main body bracket 1 through the detachable rubber plug 32. It can be understood that the above-mentioned main body bracket 1, movable bracket 2 and adjustment component 3 can be assembled to form a test vibration absorber, each of which has two detachable rubber plugs 32; wherein one end of the detachable rubber plug 32 is connected to the main body bracket 1, and the other end is connected to the sleeve 34 (for example, both ends of the detachable rubber plug 32 have a slot, one end of the detachable rubber plug 32 is connected to the main body bracket 1 through the slot, and the other end is connected to the sleeve 34 through the slot), and the movable mass block 33 is detachably mounted on the main body mass block 31, and its detachable installation method can be set according to needs, for example, Figure 1 and Figure 2 As shown, the movable mass block 33 is annular, and the movable mass block 33 is sleeved on the main mass block 31; specifically, the main mass block 31 is provided with an external thread, and the inner ring surface of the annular movable mass block 33 is provided with an internal thread, so that the movable mass block 33 and the main mass block 31 can be threadedly connected; in another embodiment, the movable mass block 33 and the main mass block 31 can also be connected by interference.

[0027] It can be understood that the frequency of the vibration absorber is mainly determined by its mass and stiffness (if the stiffness remains unchanged, the mass is inversely proportional to the frequency; if the mass remains unchanged, the stiffness is directly proportional to the frequency), and by changing the number and mass of the movable mass blocks 33 installed on the main body mass block 31, the mass of the vibration absorber can be changed, and by replacing the removable rubber plugs 32 with different rubber performance parameters in the vibration absorber, the stiffness of the vibration absorber can be changed. Furthermore, by adjusting the above-mentioned movable mass blocks 33 (the number and mass) and / or the removable rubber plugs 32 (the rubber performance parameters), the wide-band frequency of the vibration absorber can be quickly and accurately adjusted. In the present invention, different vibration absorber simulation parameters can be determined according to different NVH problem data of the vehicle, and then, corresponding to each set of vibration absorber simulation parameters, a removable rubber plug 32 with different rubber performance parameters and a movable mass block 33 of different quantity and quality are selected for the vibration absorber combination structure to assemble the adjustment component 3, and then the frequency of the vibration absorber is quickly and accurately adjusted by using the combination of the selected movable mass block 33 and the removable rubber plug 32, so that the final test vibration absorber has a frequency that can be adjusted with a large bandwidth. Specifically, the number of movable mass blocks 33 in the vibration absorber combination structure is set according to demand, and the weight of each movable mass block 33 can be the same or different. For example, each type of movable mass block 33 can be set to be stored in even numbers, and its weight is set to 50g, 100g, 200g, etc. In the assembled adjustment component 3, the total weight of all movable mass blocks 33 allows it to be adjusted within the range of 1kg to 2kg. The rubber performance parameters of different removable rubber plugs 32 need to be clearly marked.

[0028] It is understandable that the movable bracket 2 (the movable bracket 2 can be a plurality of brackets with different shapes, including Figure 1 and Figure 2 The straight plate 21 and the bent plate 22 shown in the figure, but not limited to the straight plate 21 and the bent plate 22, can be detachably connected with the main body bracket 1 by bolt connection. After selecting different detachable rubber plugs 32 and different numbers and masses of movable mass blocks 33 for the vibration absorber combination structure to assemble the adjustment component 3, it is also necessary to select different movable brackets 2 corresponding to each set of vibration absorber simulation parameters, and then use the movable brackets 2 to adapt to the vibration absorber installation requirements of different problem parts and different vehicle parts. The main body bracket 1 itself has a limiting function, which can limit the adjustment component 3 installed on the main body bracket 1 in the X and Z directions; therefore, after assembling the movable bracket 2, the adjustment component 3 and the main body bracket 1 to obtain the test vibration absorber, the rapid fine adjustment limit design of the main body bracket 1 can be used to obtain a test vibration absorber with different installation or limit designs, and finally the vibration absorber design parameters determined by the vehicle test are mass-produced with relatively optimal durability, vibration absorption and noise prevention performance.

[0029] The vibration absorber combination structure in the above-mentioned embodiment of the present invention is a modular assembly structure (a vibration absorber parts library can be set up, and all parts of the vibration absorber combination structure can be added thereto for selection). When the vibration absorber combination structure needs to be combined and assembled into different test vibration absorbers, it is only necessary to replace individual parts, thus avoiding the cost waste and cycle extension caused by the need to scrap and replace the entire vibration absorber and redesign the vibration absorber when adjusting and replacing the vibration absorber parameters in the past. In addition, the vibration absorber combination structure is easy to disassemble and flexible to install, can be used for multiple purposes, has a wide adaptability, saves a lot of cost, and shortens the development cycle.

[0030] Understandably, when the test vibration absorber is conducting a vehicle test, the main body mass block 31 and the movable mass block 33 will vibrate and displace in the vibration space formed in the main body bracket 1. If their positions are not restricted, the detachable rubber plug 32 will also be continuously deformed, and its material properties will be attenuated, and the main body mass block 31 and the movable mass block 33 will also collide with the surrounding components and make abnormal noises. Therefore, in order to prevent abnormal noises from impacts and avoid the reduction of rubber durability, it is necessary to design a reasonable vibration space (i.e., limit amount). Therefore, in this embodiment, the fixed limit displacement is changed to a variable limit displacement by combining different limit brackets to match different vibration absorber simulation parameters (limit parameters therein), thereby obtaining a test vibration absorber with different frequencies, and at the same time realizing the limit requirements with different installation gaps, determining the optimal limit parameters for the mass production design of the vibration absorber, and preventing the vibration absorber from colliding and making abnormal noises while ensuring the vibration absorption performance of the vibration absorber. Understandably, the vibration absorber combination structure of the present invention also includes a felt or rubber limit plug arranged on the main body bracket 1 to further prevent abnormal noises from metal impacts.

[0031] In one embodiment, if Figure 1 and Figure 2As shown, the main body bracket 1 includes a main bracket 11, and a first limit bracket 12 and a second limit bracket 13 relatively installed on the main bracket 11; the two sleeves 34 are respectively installed on the first limit bracket 12 and the second limit bracket 13 through the detachable rubber plug 32, and the first limit bracket 12 and the second limit bracket 13 are used to adjust the Z-direction limit amount of the adjustment component 3; wherein, the Z direction refers to the direction perpendicular to the horizontal plane. Specifically, the whole vehicle coordinate system is set, and it is assumed that the axial direction of the main body mass block 31 (that is, the axial direction of the main body mass block 31 is the X direction, and the X direction is perpendicular to the Y direction and the Z direction) is parallel to the Y direction of the whole vehicle coordinate system, and the Z direction is perpendicular to the horizontal plane; at this time, if it is necessary to adjust the limit amount in the Z direction, the first mounting hole 111 of the main bracket 11 and the first sliding hole 124 set on the first limit bracket 12 can be detachably connected by bolts, and the connection position can be at any point in the first sliding hole 124; the second mounting hole of the main bracket 11 and the second sliding hole set on the second limit bracket 13 are detachably connected by bolts, and the connection position can be at any point in the second sliding hole; in this way, the vibration space height between the first limit bracket 12, the second limit bracket 13 and the main bracket 11 (that is, the height distance between the first limit bracket 12 and the main bracket 11, and the height distance between the second limit bracket 13 and the main bracket 11) can be adjusted to match the preset Z-direction limit amount.

[0032] In one embodiment, if Figure 1 and Figure 2 As shown, the main body bracket 1 includes a main bracket 11, and a third limit bracket 14 and a fourth limit bracket 15 relatively installed on the main bracket 11; the third limit bracket 14 and the fourth limit bracket 15 are used to adjust the X-direction limit amount of the adjustment component 3; wherein the X-direction refers to the direction in the horizontal plane perpendicular to the main body mass block 31. Specifically, the whole vehicle coordinate system is set, and it is assumed that the axial direction of the main mass block 31 (that is, the axial direction of the main mass block 31 is the X direction) is parallel to the Y direction of the whole vehicle coordinate system, and the Z direction is perpendicular to the horizontal plane; at this time, if it is necessary to adjust the limit amount in the X direction, the third sliding hole 112 on the main bracket 11 and the third mounting hole 141 set on the third limit bracket 14 can be detachably connected by bolts, and the connection position can be at any point in the third sliding hole 112; the fourth sliding hole of the main bracket 11 and the fourth mounting hole set on the second limit bracket 13 are detachably connected by bolts, and the connection position can be at any point in the fourth sliding hole; in this way, the vibration space width between the first limit bracket 12, the second limit bracket 13, the third limit bracket 14, the fourth limit bracket 15 and the main bracket 11 (that is, the width distance between the third limit bracket 14 and the fourth limit bracket 15) can be adjusted to match the preset X-direction limit amount.

[0033] It can be understood that a developer layer can be coated on the inner wall of the vibration space corresponding to the main bracket 11, the first limit bracket 12, the second limit bracket 13, the third limit bracket 14, and the fourth limit bracket 15, and then after the whole vehicle test, it can be judged whether there is a collision contact based on the friction state of the developer layer, and then the current parameters can be further calibrated.

[0034] In one embodiment, the movable bracket 2 includes a straight plate 21 and a bending plate 22; the straight plate 21 is provided with a first sliding groove 211, and the bending plate 22 includes a first connecting plate 221 and a second connecting plate 222 connected at a preset angle; the first connecting plate 221 is provided with a second sliding groove 2211, and the second connecting plate 222 is provided with a connecting hole 2221; the straight plate 21 is slidably connected to the main body bracket 1 or the connecting hole 2221 by a first screw passing through the first sliding groove 211; the bending plate 22 is slidably connected to the main body bracket 1 by a second screw passing through the second sliding groove 2211. That is, in this embodiment, the bending plate 22 and the straight plate 21 are designed to realize the installation between the test shock absorber and the vehicle in different directions, angles, and positions. For example, to realize the mobile matching of the installation point in the XY plane, to realize the mobile installation in the X direction, to realize the mobile matching of the installation point in the YZ plane, etc.

[0035] Specifically, Figure 2 As shown, the vehicle coordinate system is set, and it is assumed that the axial direction of the main body mass block 31 (that is, the axial direction of the main body mass block 31 is the X direction) is parallel to the Y direction of the vehicle coordinate system, and the Z direction is perpendicular to the horizontal plane; it can be understood that the first limit bracket 12, the second limit bracket 13, the third limit bracket 14 and the fourth limit bracket 15 can be installed on the main bracket 11 in parallel with the Z direction in the initial state.

[0036] When it is necessary to realize the movement matching of the installation point in the XY plane through the straight plate 21, that is, when it is necessary to install the test shock absorber in the preset space of the test vehicle and realize the movement of the installation point in the XY plane, the first sliding groove 211 on the straight plate 21 can be connected to the first top surface flange 122 arranged on the first limiting bracket 12 (the first limiting bracket 12 includes a first main body 121 connected to the main bracket 11 and parallel to the Z direction, and a first top surface flange 122 connected to the first main body 121 and parallel to the Y direction, and the first top surface flange 122 extends toward the second limiting bracket 13) by bolts. After that, a circular maximum installation area can be formed in the XY plane with the first through hole 123 as the origin and the length of the first sliding groove 211 as the radius. Similarly, when it is necessary to realize the mobile matching of the installation point in the XY plane, the first sliding groove 211 on the straight plate 21 can also be connected with the second through hole on the second top surface flange of the second limit bracket 13 (the second limit bracket 13 includes a second main body connected to the main bracket 11 and parallel to the Z direction, and a second top surface flange connected to the second main body and parallel to the Y direction, and the second top surface flange extends toward the first limit bracket 12) by bolt connection, and then, a circular maximum installation area can be formed in the XY plane with the second through hole as the origin and the length of the second sliding groove 2211 as the radius. It can be understood that in order to realize the mobile matching of the installation point in the XY plane, a straight plate 21 can also be installed on both the first top surface flange 122 and the second top surface flange.

[0037] When it is necessary to realize X-direction movable installation through the bending plate 22, that is, when it is necessary to install the test vibration absorber in the preset space of the test vehicle and realize the movement of the test vibration absorber in the X-direction, the second sliding groove 2211 on the bending plate 22 and the third through hole 125 on the first limiting bracket 12 (the first limiting bracket 12 includes a first main body portion 121 connected to the main bracket 11 and parallel to the Z-direction, and the first main body portion 121 is provided with a third through hole 125) are connected by bolts, and the connecting hole 2221 is connected to the body of the test vehicle; at this time, since the second sliding groove 2211 is arranged parallel to the X-direction and the connection position can be at any place in the second sliding groove 2211, the movement of the test vibration absorber in the X-direction can be realized through the bending plate 22. Similarly, when it is necessary to realize X-direction movable installation through the bending plate 22, the second sliding groove 2211 on the bending plate 22 can be connected to the fourth through hole on the second limit bracket 13 (the second limit bracket 13 includes a second main body connected to the main bracket 11 and parallel to the Z direction, and the second main body is provided with a fourth through hole) through bolts, and the connecting hole 2221 is connected to the body of the test vehicle; at this time, since the second sliding groove 2211 is arranged parallel to the X direction, and the connection position can be at any point in the second sliding groove 2211, the movement of the test vibration absorber in the X direction can be realized through the bending plate 22. It can be understood that in order to realize X-direction movable installation, a bending plate 22 can also be installed on both the first main body 121 and the second main body.

[0038] When it is necessary to realize the movement matching of the installation point in the YZ plane simultaneously through the straight plate 21 and the bending plate 22, the second sliding groove 2211 on the bending plate 22 can be connected to the third through hole 125 on the first limiting bracket 12 by bolts (the connection position can be anywhere in the second sliding groove 2211), and the first sliding groove 211 of the straight plate 21 is connected to the connecting hole 2221 by bolts (the connection position can be anywhere in the first sliding groove 211); at this time, the second sliding groove 2211 is set parallel to the X direction, and the first sliding groove 211 is set parallel to the Y direction. Therefore, the movement of the installation point in the YZ plane can be realized simultaneously through the above-mentioned straight plate 21 and the bending plate 22. Similarly, when it is necessary to realize the movement and matching of the installation point in the YZ plane simultaneously through the straight plate 21 and the bent plate 22, the second sliding groove 2211 on the bent plate 22 can also be connected to the fourth through hole on the second limit bracket 13 by bolts (the connection position can be anywhere in the second sliding groove 2211), and the first sliding groove 211 of the straight plate 21 is connected to the connection hole 2221 by bolts (the connection position can be anywhere in the first sliding groove 211); at this time, the second sliding groove 2211 is set parallel to the X direction, and the first sliding groove 211 is set parallel to the Y direction. Therefore, the movement of the installation point in the YZ plane can be realized simultaneously through the above-mentioned straight plate 21 and the bent plate 22. It can be understood that in order to realize the movement of the installation point in the YZ plane, a bent plate 22 and a straight plate 21 can also be installed on the first main body 121 and the second main body, respectively.

[0039] When it is necessary to realize the movement matching of the installation point in the XZ plane through the straight plate 21, that is, when it is necessary to install the test vibration absorber in the preset space of the test vehicle and realize the movement of the installation point in the XZ plane, the first sliding groove 211 on the straight plate 21 and the third through hole 125 on the first limit bracket 12 (the first limit bracket 12 includes a first main body 121 connected to the main bracket 11 and parallel to the Z direction, and the first main body 121 is provided with a third through hole 125) can be connected by bolts, and then, a circular maximum installation area can be formed in the XZ plane with the third through hole 125 as the origin and the length of the first sliding groove 211 as the radius. Similarly. When it is necessary to realize the mobile matching of the installation point in the XZ plane through the straight plate 21, the first sliding groove 211 on the straight plate 21 can also be connected with the fourth through hole on the second limit bracket 13 (the second limit bracket 13 includes a second main body connected to the main bracket 11 and parallel to the Z direction, and the second main body is provided with a fourth through hole) by bolts, and then, a circular maximum installation area can be formed in the XZ plane with the fourth through hole as the origin and the length of the first sliding groove 211 as the radius. It can be understood that in order to realize the mobile matching of the installation point in the XZ plane, a straight plate 21 can also be installed on both the first main body 121 and the second main body.

[0040] In one embodiment, if Figure 3 As shown, a vibration absorber parameter processing method is provided, comprising the following steps:

[0041] S100: Determine at least one set of vibration absorber simulation parameters based on the NVH (Noise, Vibration, Harshness) problem data of the vehicle; specifically, the NVH problem data includes the NVH problem existing in the vehicle and the installation space parameters related to the NVH problem (such as the specific installation space parameters reserved for the vibration absorber on the vehicle, according to which the space parameters and limit parameters in the vibration absorber simulation parameters can be determined, wherein the space parameters are used to characterize the parameters corresponding to the preset space in the test vehicle, and the limit parameters are used to characterize the relevant parameters of the vibration space corresponding to the installation of the main mass block 31 and the active mass block 33), the problem frequency (referring to the N currently existing in the vehicle); The vibration and noise frequency value corresponding to the VH problem, based on which the frequency parameters in the vibration absorber simulation parameters can be determined. Generally, the vibration and noise frequency value corresponding to NVH problems of seats, door covers, and ceiling sheet metal problems is between 10Hz and 50Hz, and the vibration absorber frequency in the theoretical frequency parameters is valid as long as the difference between the problem frequency is ±3Hz), system mass (system mass refers to the original system mass corresponding to the NVH problem, and there is a certain ratio between the vibration absorber mass and the system mass. For example, the ratio of the system mass to the vibration absorber mass can be 0.02 to 0.1 to exert the vibration absorber effect. Therefore, the mass parameters in the vibration absorber simulation parameters can be determined based on the above system mass) and other data necessary for designing vibration absorbers.

[0042] In the present invention, a set of vibration absorber simulation parameters can be set according to the problem frequency corresponding to an NVH problem; or a set of vibration absorber simulation parameters can be set according to multiple NVH problems based on the actual design requirements of the balanced vibration absorber. For example, the system mass of the vibration absorber is 5kg, but the installation space parameters of the actual design indicate that only a 3kg mass block (the sum of the masses of the main mass block 31 and the movable mass block 33) is allowed to be arranged in the vehicle. At this time, it is necessary to adjust the rubber performance parameters of the detachable rubber plug 32, and then adjust the frequency of the test vibration absorber through the above-mentioned adjustment of the rubber performance parameters of the detachable rubber plug 32 and the selection of the number and mass of the movable mass blocks 33 to obtain the optimal vibration absorption effect.

[0043] S200: Conduct a vehicle test on a test vehicle equipped with a test vibration absorber to obtain a vehicle test result corresponding to the test vibration absorber; the test vibration absorber is obtained by assembling a vibration absorber combination structure according to the vibration absorber simulation parameters; and one test vibration absorber is assembled according to each set of the vibration absorber simulation parameters. Specifically, before conducting the vehicle test, it is necessary to select suitable vibration absorber parts in the vibration absorber combination structure from the vibration absorber parts library to assemble the test vibration absorber. In which, referring to the above specific description of the vibration absorber combination structure, different vibration absorber simulation parameters can be determined according to different NVH problem data of the vehicle, and then, corresponding to each set of vibration absorber simulation parameters, a detachable rubber plug 32 with different rubber performance parameters and a movable mass block 33 with different numbers and masses are selected for the vibration absorber combination structure to assemble the adjustment component 3 in a targeted manner, and then the frequency of the vibration absorber is quickly and accurately adjusted by using the combination of the selected movable mass block 33 and the detachable rubber plug 32, so that the final test vibration absorber has a frequency that can be adjusted with a large bandwidth. The movable bracket 2 (the movable bracket 2 can be a plurality of brackets with different shapes, such as a straight plate 21 and a bent plate 22) and the main body bracket 1 can be detachably connected by bolt connection. After selecting different detachable rubber plugs 32 and movable mass blocks 33 of different numbers and masses for the vibration absorber combination structure to assemble the adjustment component 3, it is necessary to select different movable brackets 2 corresponding to each set of vibration absorber simulation parameters, and then use the movable bracket 2 to adapt to the vibration absorber installation requirements of different problem parts and different vehicle parts. The main body bracket 1 itself has a limiting function, which can limit the adjustment component 3 installed on the main body bracket 1 in the X and Z directions; therefore, after assembling the movable bracket 2, the adjustment component 3 and the main body bracket 1 to obtain the test vibration absorber, the rapid fine adjustment limit design of the main body bracket 1 can be used to obtain a test vibration absorber with different installation or limit designs, and then finally the vibration absorber design parameters determined by the vehicle test are used to mass-produce a vibration absorber with relatively optimal durability, vibration absorption and noise prevention performance, so that the vibration absorber performance meets the vehicle development goals. The vehicle test is a conventional method for those skilled in the art, and will not be described in detail again.

The system mass refers to the original system mass corresponding to the NVH problem. There is a certain ratio between the vibration absorber mass and the system mass. For example, the ratio of the system mass to the vibration absorber mass can be 0.02 to 0.1 to exert the vibration absorber effect. The frequency parameter can be determined according to the vibration noise frequency value in the NVH problem data. The vibration absorber frequency in the frequency parameter is valid if the difference between the problem frequency and the problem frequency is ±3Hz. (Generally, the vibration noise frequency value (that is, the problem frequency) corresponding to the NVH problem of seats, door covers, and ceiling sheet metal problems is between 10Hz and 50Hz.

[0048] S202, controlling the preset assembly equipment to assemble the main body bracket 1 of the vibration absorber combination structure according to the limit parameters, and installing the adjustment component 3 on the main body bracket 1; specifically, the limit parameters can be determined according to the installation space parameters in the NVH problem data, wherein the limit parameters are used to characterize the relevant parameters of the vibration space corresponding to the installation of the main mass block 31 and the movable mass block 33.

[0050] S204, conduct a whole vehicle test on the test vehicle equipped with the test vibration absorber to obtain a whole vehicle test result corresponding to the test vibration absorber; the test vibration absorber is installed in a preset space of the test vehicle through the movable bracket 2. After the test vibration absorber is obtained by assembling the movable bracket 2, the adjustment component 3 and the main body bracket 1, the test vibration absorber with different installation or limit designs can be obtained by using the fast fine adjustment limit design of the main body bracket 1, and then finally the vibration absorber design parameters determined by the whole vehicle test are used to mass produce the vibration absorber with relatively optimal durability, vibration absorption and abnormal noise prevention performance, so that the vibration absorber performance meets the whole vehicle development goals.

[0051] In one embodiment, the adjustment component 3 includes a body mass block 31, a detachable rubber plug 32, at least one movable mass block 33 and two sleeves 34; the step S201, that is, the control of the preset assembly device to assemble the adjustment component 3 of the vibration absorber combination structure according to the mass parameter and the frequency parameter, includes:

[0052] S2011, select the movable mass block 33 according to the mass parameter, and control the preset assembly equipment to install the selected movable mass blocks 33 on the main mass block 31 to obtain a mass module; it is understandable that the weight of each movable mass block 33 can be the same or different, for example, each movable mass block 33 can be set to be stored in even numbers, and its weight is set to 50g, 100g, 200g, etc. In this embodiment, since the mass of the main mass block 31 is fixed, the number of movable mass blocks 33 actually required and the mass of each movable mass block 33 can be determined according to the mass parameter, and then the selected movable mass block 33 is installed on the main mass block 31 to obtain a mass module. Among them, the movable mass block 33 can be detachably installed on the main mass block 31, and its detachable installation method can be set according to the needs, for example, Figure 1 and Figure 2 As shown in the figure, the movable mass block 33 is annular, and the movable mass block 33 is sleeved on the main mass block 31; specifically, the main mass block 31 is provided with an external thread, and the inner ring surface of the annular movable mass block 33 is provided with an internal thread, so that the movable mass block 33 and the main mass block 31 can be threadedly connected; in another embodiment, an interference connection between the movable mass block 33 and the main mass block 31 is also possible.

[0053] S2012, obtaining the frequency influence coefficient of the mass module, and determining the rubber performance parameters according to the frequency influence coefficient and the frequency parameters; it is understandable that since the frequency of the vibration absorber is mainly determined by its mass and stiffness (stiffness remains unchanged, mass is inversely proportional to frequency; mass remains unchanged, stiffness is proportional to frequency), and the mass of the mass module obtained by the above combination has been determined, therefore, the frequency influence coefficient corresponding to the mass module will also be determined accordingly, and then, in order to finally match the frequency parameters, the stiffness of the test vibration absorber can be changed by replacing the removable rubber plug 32 with different rubber performance parameters. Therefore, in this step, after selecting different numbers and masses of active mass blocks 33 to form the mass module, it is also necessary to selectively select removable rubber plugs 32 with different rubber performance parameters for the vibration absorber combination structure to assemble the adjustment component 3, and then use the selected active mass block 33 and the removable rubber plug 32 combination to quickly and accurately adjust the frequency of the vibration absorber, so that the final test vibration absorber has a frequency that can be adjusted with a wide bandwidth.

[0057] S2021, control the preset assembly equipment to relatively install the first limit bracket 12 and the second limit bracket 13 on the main bracket 11; specifically, set the vehicle coordinate system, and assume that the axial direction of the body mass block 31 (that is, the axial direction of the body mass block 31 is the X direction) is parallel to the Y direction of the vehicle coordinate system, and the Z direction is perpendicular to the horizontal plane; the first limit bracket 12 and the second limit bracket 13 are relatively installed on the main bracket 11.
