The disc brake mounting base 14 includes a driving member, and the power output end of the driving member is connected to the disc brake 200. The driving member is electrically connected to the control device 30 to push the brake pad of the disc brake 200 toward the metal disk 13 under the control of the control device. The driving member may include a cylinder or an electric push rod, but is not limited to this; the detection device 20 is electrically connected to the control device 30, and is used to detect the state of the metal disk 13 during braking, for example, it may include sensors such as speed sensors, temperature sensors, and noise detectors; the control device 30 can be a laptop computer, a desktop computer, a computing device or other processing equipment connected to a wireless modem, a computer, a laptop computer, etc.
[0088] In order to better understand the brake disc brake performance detection method provided in the embodiment of the present application, the specific implementation process of the brake disc brake performance detection method provided in the embodiment of the present application is exemplarily introduced below.
[0089] Figure 1 A schematic flow chart of a brake disc brake performance detection method provided in an embodiment of the present application is shown. The brake disc brake performance detection method includes:
[0090] S100 , controlling the disc brake performance testing device 100 to perform a first operation; wherein the first operation is controlling the testing device 10 to rotate.
[0091] It can be understood that the brake disc brake performance testing equipment 100 can be provided with a physical button, and by pressing the physical button, the drive motor of the test device 10 is started and the metal disk 13 is driven to start rotating; or a signal can be sent to the data processing component of the test device 10 through the control device 30 to start the drive motor of the test device 10 and drive the metal disk 13 to start rotating, but it is not limited to this.
[0092] As an optional embodiment of this application, please refer to Figure 2S100: Control the brake disc brake performance testing device 100 to perform a first operation, including:
[0093] S110, obtaining test condition information; wherein the test condition information includes road condition information, climate information and vehicle usage information.
[0094] It is understood that the test condition information is information used to simulate the actual usage of the disc brake 200. For example, road condition information may include road material, road slope, and road humidity; climate information may include weather conditions, wind speed, and the like; and vehicle usage may include carrying passengers, livestock, fragile items, or heavy cargo. The test condition information can be manually input with specific road condition information, climate information, and vehicle usage information. Alternatively, a road condition information database comprising multiple road condition information, a climate information database comprising multiple climate information, and a vehicle usage information database comprising multiple vehicle usage information can be separately established, and a computing device can be used to randomly select one data item from each of the three databases and combine the three data items into the test condition information, but the present invention is not limited thereto.
[0095] S120: Obtain test speed data according to the test condition information.
[0096] For example, you can consult traffic regulations or relevant materials for safe vehicle speeds under different conditions. For example, you can assume that the test condition information is "dry asphalt road, urban road, sunny day, manned two-wheeled motorcycle", then the test speed data can be "60km / h"; or assume that the test condition information is "wet cement road, rural road, light rain, cargo three-wheeled motorcycle", then the test speed can be "40km / h", but not limited to this.
[0097] S130 , according to the test speed data, controlling the brake disc brake performance testing device 100 to perform a first operation to adjust the speed of the brake disc brake performance testing device 100 to a test speed corresponding to the test speed data.
[0098] For example, based on the test speed data, the metal disk 13 of the test device 10 is accelerated to a corresponding rotational speed. The rotational speed of the metal disk 13 = the test speed data * the tire circumference * the rotational speed conversion factor. For example, if the test speed data is "60 km / h", the diameter of a common motorcycle tire is 18 inches (i.e., 0.46 meters), the tire circumference is 1.45 meters (0.46*π≈1.45), and the rotational speed of the metal disk 13 is 690 rpm (60*1000 / 1.45 / 60≈690). Alternatively, if the test speed data is "40 km / h", the rotational speed of the metal disk 13 is 460 rpm (40*1000 / 1.45 / 60≈460). It should be noted that the numerical values given above do not represent actual data and are set for ease of understanding only. The specific data depends on the actual situation and will not be detailed here.
[0099] With such a setting, by obtaining the test condition information and then obtaining the test speed data from the test condition information, the metal disk 13 of the test device 10 is accelerated to a rotation speed corresponding to the test speed data. This allows the prerequisites for the test to be formulated, which is more in line with actual usage, reduces the errors caused by the subjective intervention of the experimental operator, and makes the subsequent brake disc brake performance test results more accurate.
[0100] S200, controls the brake disc brake performance testing equipment to perform a second operation on the disc brake 200; wherein, the disc brake 200 is detachably arranged on one side of the testing device 10, and the disc brake 200 can clamp the testing device 10; the second operation is to push the brake pad of the disc brake 200 to clamp the testing device 10, so as to slow down the rotation of the testing device 10.
[0101] It will be understood that the disc brake 200 is mounted on the disc brake mounting base 14, and the control device of the brake disc brake performance testing equipment controls the driving member on the disc brake mounting base 14 to push the brake pads of the disc brake 200 toward the metal disk 13, thereby braking the metal disk 13. The pressure data applied to the brake pads of the disc brake 200 is a preset value that can be selected by the experimenter or set to the rated working pressure of the disc brake 200, but is not limited thereto.
[0102] As an optional embodiment of this application, please refer to Figure 3 S200, controlling the brake disc brake performance testing device to perform a second operation on the disc brake 200, including:
[0103] S210 , obtaining a preset clamping force; wherein the preset clamping force is the pressure of the disc brake 200 on the brake disc brake performance testing device 100 .
[0104] It is understandable that the preset clamping force can be set by an experimenter, or the rated working pressure can be obtained by referring to the product manual of the disc brake 200, but is not limited thereto.
[0105] S220 , controlling the disc brake 200 to perform a second operation according to the preset clamping force until the speed of the disc brake performance testing device 100 is zero.
[0106] It can be understood that the brake pads of the disc brake 200 clamp the metal disc 13 with a preset clamping force, and the friction between the brake pads and the metal disc 13 can gradually stop the metal disc from rotating.
[0107] With such a setting, by selecting a preset clamping force and controlling the disc brake 200 to clamp the metal disc 13 for braking, the variables in the detection process can be reduced, the reliability of the detection results can be improved, the efficiency of the detection work can be improved, the possibility of human operation errors can be reduced, and the consistency of the detection work can be improved.
[0108] S300 , obtaining status information of the brake disc brake performance testing device 100 ; the status information is used to indicate changes in the body and surroundings of the testing device 10 when the testing device 10 is clamped by the disc brake 200 .
[0109] It can be understood that the status information of the testing device 10 can be obtained through sensors such as the speed sensor, temperature sensor, and noise detector in the detection device 20, such as the rotation speed data of the metal disk 13, the acceleration data of the metal disk 13, the temperature data of the surface of the metal disk 13, and the volume data within 5 cm around the metal disk 13.
[0110] As an optional embodiment of this application, please refer to Figure 4 S300, obtaining status information of the brake disc brake performance detection device 100, including:
[0111] S310 , obtaining deceleration data of the disc brake performance testing device 100 .
[0112] For example, an accelerometer can be placed above the metal disk 13 and electrically connected to the control device 30. The angular acceleration of the metal disk 13 can be directly obtained through the accelerometer, and then the angular acceleration can be converted into deceleration data of the motorcycle. For example, if the angular acceleration of the metal disk 13 is "-5 rad / s²" and the radius of the motorcycle wheel is 0.23 m, then the deceleration data of the motorcycle is 1.15 m / s² (-5*0.23=-1.15), that is, 14.9 km / h² (1.15 / 1000*3600*3600=14.9); or if the angular acceleration of the metal disk 13 is "-10 rad / s²" and the radius of the motorcycle wheel is 0.23 m, then the deceleration data of the motorcycle is 2.3 m / s² (-10*0.23=-2.3), that is, 29.8 km / h² (2.3 / 1000*3600*3600=29.8). It should be noted that the above given values do not represent actual data, but are set for ease of understanding. The specific data depends on the actual situation and will not be repeated here.
[0113] S320: Obtain brake volume data generated by the disc brake 200.
[0114] It is understood that a decibel meter or noise volume detector can be placed above the metal disc 13 and electrically connected to the control device 30 to detect and determine the volume generated by the disc brake 200 during braking, thereby obtaining brake volume data. The sound pickup range for the brake volume data needs to be set within the same range, and can be set to collect the sound at the surface of the disc brake 200 or the metal disc 13, or 5 cm above the disc brake 200 or the metal disc 13. The specific sound pickup range depends on the actual situation.
[0115] S330: Confirm the deceleration data and the brake volume data as status information.
[0116] With such a configuration, the deceleration data and the braking volume data are obtained through the detection device 20, and the deceleration data and the braking volume data are confirmed as status information. Different actual usage environments can be simulated to detect the disc brake 200, and the braking performance of the disc brake 200 can be further judged from the deceleration data and the braking volume data. The driving experience of vehicles using the disc brake 200 can be intuitively compared, and comfort is also used as an important evaluation criterion for the braking of the disc brake 200, which is conducive to improving the driving experience of the driver, passengers, and cargo, and improving the safety of the braking of the disc brake 200.
[0117] S400 , obtaining the state information of the object according to the state information; the state information of the object is used to indicate the state of the object in the vehicle using the disc brake 200 .
[0118] It can be understood that the status information of the brake disc brake performance detection equipment 100 detected by the detection device 20 can be calculated to obtain the status information of the vehicle using the same disc brake 200, and then the status information of the load carried by the vehicle can be obtained through the status information of the vehicle using the same disc brake 200.
[0119] As an optional embodiment of this application, please refer to Figure 5 S400: Obtaining the bearer status information according to the status information, including:
[0120] S410: Obtain load data based on the deceleration data.
[0121] It is understandable that when the disc brake 200 is braking, the metal disc 13 will gradually slow down. Assuming that the vehicle equipped with the disc brake 200 will also gradually slow down, the load inside the vehicle will be subjected to increased pressure due to inertia, and the force data of the load will increase.
[0122] Optionally, see Figure 6 S410: Obtaining load force data based on the deceleration data, including:
[0123] S411 , obtaining mass data of the carried object and contact area data between the carried object and the vehicle.
[0124] For example, the mass and contact area data of the load can be obtained by actually measuring the load, such as by weighing the load using a scale and measuring the contact area data between the load and the vehicle using a pressure distribution measurement system. Alternatively, the mass and contact area data can be obtained by randomly selecting from a preset load information database on the control device 30, where the load information database may be a pre-established database containing mass data of multiple human bodies (or goods) and corresponding contact area data. For example, assuming the load is an "adult male," the mass data can be set to "70 kg" and the contact area data to "500 cm²." Alternatively, assuming the load is a "computer case," the mass data can be set to "15 kg" and the contact area data to "750 cm²." It should be noted that the numerical values given above do not represent actual data and are provided for ease of understanding only. The specific data will depend on the actual situation and will not be detailed here.
[0125] S412: Calculate the load-bearing object force data based on the mass data, the contact area data, and the deceleration data.
[0126] For example, the support force of the vehicle on the load can be obtained based on the mass data and deceleration data, and the pressure between the load and the vehicle can be obtained based on the support force and contact area data, that is, the force data of the load. For example, assuming that the mass data is "70kg", the contact area data is "500cm²" (0.05m²), and the deceleration data is 1.15m / s² (14.9km / h²), according to the formula F=m*a, where F is the support force of the vehicle on the load, m is the mass data of the load, and a is the deceleration data of the vehicle during braking, it can be obtained that the support force of the vehicle on the load during braking is 80.5N (70*1.15=80.5). According to the formula P=F / S, where P Where is the load force (the load is subject to pressure from the vehicle), F is the vehicle's support force on the load, and S is the contact area between the load and the vehicle. The calculated load force is 1610 Pa (80.5 / 0.05 = 1610). Alternatively, assuming a mass of 15 kg, a contact area of 745 cm² (0.075 m²), and a deceleration of 2.3 m / s² (29.8 km / h²), using the formula F = m*a, the load force applied by the vehicle during braking is 34.5 N (15 * 2.3 = 34.5). Using the formula P = F / S, the calculated load force is 460 Pa (34.5 / 0.075 = 460). It should be noted that the values given above do not represent actual data and are provided for ease of understanding only. Specific data will depend on actual conditions and will not be detailed here.
[0127] With such a setting, by calculating the pressure exerted on the load when the disc brake 200 is applied, it is possible to determine whether the vehicle can ensure the safety of its load at the same time when braking. This is helpful in determining the comfort and safety of the vehicle braked with this disc brake 200, and is helpful in more comprehensively evaluating the braking performance of the disc brake 200, helping testers understand the performance of the disc brake 200 under actual usage conditions.
[0128] S420, obtaining the carried object's sound reception volume data according to the braking volume data.
[0129] Exemplarily, the brake volume data may be data obtained by picking up sound on the surface of the disc brake 200 or the metal disk 13 or within 5 cm of the surface. In actual situations, there are other structures of the vehicle between the carrier and the disc brake 200. The brake volume data may be modified according to different actual situations to obtain the carrier sound pickup volume data.
[0130] Optionally, see Figure 7 S420, obtaining the object's radio volume data based on the braking volume data, including:
[0131] S421, obtaining placement information of the load;
[0132] It is understood that the load placement location information can be manually input, or a preset placement location database containing multiple placement location information can be used, and a piece of placement location information can be randomly selected from the placement location database. The multiple placement location information can be information collected by testers during multiple experiments, but is not limited to this. For example, the placement location information can be "driver's seat, 0.5m from the disc brake," "back seat, 0.7m from the disc brake," or "cargo box, 1m from the disc brake," but is not limited to these.
[0133] S422, obtaining the carried object's sound reception volume data according to the braking volume data and the placement position information.
[0134] For example, as sound propagates in the atmosphere, it gradually attenuates with increasing distance. The volume at the test point can be calculated based on the relative distance between the sound source and the test point. For example, assuming the brake volume data is "80 decibels" and the installation location information is "driving seat, 0.5m away from the disc brake", the formula for the attenuation value caused by the sound source increasing with the propagation distance is:
[0135]
[0136] , where A div Where is the volume attenuation value, and r is the distance from the sound source to the test point. The resulting attenuation value is -11dB (10*lg(1 / 4 / π / 0.25=-4.97)), and the volume data for the load is 75.03dB (80-4.97=75.03). Alternatively, assuming the braking volume data is 110dB and the installation location is "cargo box, 1m from the disc brake," the resulting attenuation value is 11dB (10*lg(1 / 4 / π / 1)=-11)), and the volume data for the load is 99dB (110-11=99). It should be noted that the values given above are not representative of actual data and are provided for ease of understanding only. Specific data will vary depending on actual conditions and will not be detailed here.
[0137] With such a setting, the noise generated by the disc brake 200 during braking can be calculated through the placement position information of the carrier, and the volume data of the carrier when it reaches the sound receiving point of the carrier. In this way, the noise generated by the disc brake 200 received by the carrier at different positions under different conditions can be calculated, which is conducive to accurately judging the noise level received by the carrier, and then judging the degree to which the carrier is affected by the noise through the noise level. It can be convenient for experimenters to judge the comfort of the disc brake 200 during braking, which is conducive to a more comprehensive evaluation of the braking performance of the disc brake 200, and helps testers understand the performance of the disc brake 200 under actual usage conditions.
[0138] S430: Determine the load-bearing object force data and the load-bearing object sound volume data as load-bearing object state information.
[0139] With such a setting, the load-bearing object force data is obtained through the deceleration data, and the load-bearing object sound volume data is obtained through the braking volume data. The load-bearing object force data and the load-bearing object sound volume data are determined as the load-bearing object state information, and the state of the load-bearing object can be quantified. The tester can clearly and accurately see the state of the load-bearing object when using the disc brake 200 for braking, and intuitively compare the differences in the state of the load-bearing object under different braking conditions, reduce the error of subjective judgment, and improve the accuracy and reliability of the test results. The quantified data is easy to analyze and is conducive to statistical analysis of the data to discover the correlation between various test conditions and test results, and then deduce the improvement direction of the disc brake 200.
[0140] S500 , obtaining a braking performance evaluation result of the disc brake 200 according to the state information of the load.
[0141] It can be understood that based on the load status information, the comfort and safety level of the load can be known, and the braking performance of the disc brake 200 can be evaluated based on the comfort and safety level of the load. For example, the braking performance evaluation result can be rated as "good", "medium", "poor" according to the performance of comfort and safety, or "A", "B", "C", but not limited to this.
[0142] As an optional embodiment of this application, please refer to Figure 8 S500: Obtaining a braking performance evaluation result of the disc brake 200 based on the load state information, including:
[0143] S510, obtaining body sensation evaluation information based on the load-bearing object force data;
[0144] It can be understood that the somatosensory evaluation information represents the pressure situation on the surface of the carrier when the pressure generated by the inertia of the disc brake 200 acts on the surface of the carrier. For example, when the carrier is a living organism, the somatosensory evaluation information can be "painful", "comfortable", etc.; when the carrier is an object, the somatosensory evaluation information can be "bearable", "about to break", "unbearable", etc.
[0145] In some embodiments, the brake disc brake performance detection method further includes:
[0146] S10, obtaining carrier information according to the test condition information; wherein the carrier information includes carrier category information.
[0147] It is understood that the category information of the carried object is used to indicate the type of carried object. The description of the carried object can be extracted from the test condition information to obtain the carried object category information. For example, based on the test condition information of "dry asphalt road, urban road, sunny day, two-wheeled motorcycle with only one driver," the carried object category information can be obtained as "adult." Alternatively, based on the test condition information of "wet cement road, rural road, light rain, three-wheeled motorcycle carrying glass products," the carried object category information can be obtained as "person" and "glass products."
[0148] Optionally, see Figure 9 S510: Obtaining body sensory evaluation information based on the load-bearing object force data, including:
[0149] S511, obtaining maximum bearing pressure data of the load according to the load category information;
[0150] It is understood that maximum pressure data represents the maximum pressure within the load-bearing range, and different types of load-bearing objects have different maximum pressure data. The maximum pressure data of a load-bearing object can be obtained by conducting experiments in the laboratory using an ErgoLAB BPMS pressure distribution tester on multiple subjects, measuring the changes in the subjects' performance under different pressures to determine their maximum pressure data; or by using a short rod with a rubber tip with a flat surface area of 1 cm² at the end, pressing the tip against the surface of the subject and gradually increasing the pressure, while collecting various physical indicators of the subject during the experiment to obtain their maximum pressure data, but the present invention is not limited to these.
[0151] S512, calculating the ratio of the load-bearing object force data to the maximum load-bearing data to obtain a body comfort value;
[0152] For example, the perceived comfort value is data used to reflect whether a load is comfortable under the influence of force. When the perceived comfort value is obtained by dividing the load force data by the maximum pressure data, the closer the perceived comfort value is to "0", the more comfortable the load is; the closer the perceived comfort value is to "1", the less comfortable the load is. If the perceived comfort value is greater than "1", it means that the load force data exceeds the maximum pressure data, and the load may be "unsafe". For example, if the load force data is "1610Pa" and the maximum pressure data is "2000Pa", the perceived comfort value is "0.805 (1610 / 2000=0.805)"; or if the load force data is "460Pa" and the maximum pressure data is "1000Pa", the perceived comfort value is "0.46 (460 / 1000=0.46)". It should be noted that the above given values do not represent actual data, but are set for ease of understanding. The specific data depends on the actual situation and will not be repeated here.
[0153] S513: Obtaining somatosensory evaluation information according to the somatosensory comfort value.
[0154] For example, a somatosensory evaluation table (Table 1) can be established, and then the somatosensory comfort value can be matched in the somatosensory evaluation table to obtain somatosensory evaluation information. As shown in Table 1:
[0155] Table 1:
[0156] Physical comfort value Physical evaluation information 0~0.5 Comfort 0.5~0.8 Slight pain 0.8~1 pain 1 or more severe pain
[0157] According to Table 1, when the somatosensory comfort value is "0.805", the somatosensory evaluation information is "pain"; when the somatosensory comfort value is "0.46", the somatosensory evaluation information is "comfortable".
[0158] With this arrangement, physical evaluation information is obtained through the load-bearing object force data, and the load-bearing object force data is converted into the physical feeling of the load-bearing object, which clearly defines the impact of different values on the load-bearing object. This can enhance the interpretability of the test results, facilitate the summary of the test results, and thus obtain an intuitive evaluation of the disc brake performance.
[0159] S520: Obtain hearing evaluation information based on the sound reception volume data of the carrier.
[0160] It can be understood that the auditory evaluation information represents the state of the supported object affected by the sound when the volume generated by the disc brake 200 is transmitted to the supported object. For example, the auditory evaluation information can be "comfortable", "loud", "harsh", "painful", etc.
[0161] Optionally, see Figure 10 S520: Obtaining hearing evaluation information based on the volume data of the carried object, including:
[0162] S521, obtaining maximum radio data that can be received by the bearer according to the bearer category information;
[0163] It's understandable that different types of loads have varying tolerances to noise and therefore have different maximum sound reception thresholds. For example, the maximum sound reception threshold for adults is 100dB, while that for animals like cattle and sheep is 80dB. Cargo is virtually unaffected by sound.
[0164] S522, calculating the ratio of the volume data of the carried object to the maximum volume data, and obtaining a listening comfort value.
[0165] For example, the hearing comfort value is used to reflect the comfort of a load under the influence of noise. When the hearing comfort value is calculated by dividing the load's audio volume by the maximum receivable volume, the closer the value is to 0, the more comfortable the load is; the closer the value is to 1, the less comfortable the load is. If the hearing comfort value is greater than 1, it indicates that the load's audio volume exceeds the maximum receivable volume, potentially making the load unsafe. For example, if the load's audio volume is 75.03dB and the maximum receivable volume is 100dB, the hearing comfort value is 0.75 (75.03 / 100 = 0.75). Alternatively, if the load's audio volume is 99dB and the maximum receivable volume is 80dB, the hearing comfort value is 1.24 (99 / 80 = 1.24). It should be noted that the above given values do not represent actual data, but are set for ease of understanding. The specific data depends on the actual situation and will not be repeated here.
[0166] S523: Obtain hearing evaluation information according to the hearing comfort value.
[0167] For example, a hearing evaluation table (Table 2) can be established, and then matching can be performed in the hearing evaluation table according to the hearing comfort value to obtain hearing evaluation information. As shown in Table 2:
[0168] Table 2:
[0169] Listening comfort value Listening evaluation information 0~0.5 Comfort 0.5~0.8 Louder 0.8~1 Harsh 1 or more stinging
[0170] According to Table 2, when the hearing comfort value is "0.75", the hearing evaluation information is "loud"; when the hearing comfort value is "1.24", the hearing evaluation information is "stinging".
[0171] S530 : Obtain a braking performance evaluation result based on the physical evaluation information and the auditory evaluation information.
[0172] It can be understood that the braking performance evaluation result represents the comfort and safety of the vehicle when the disc brake 200 is braking, which is a combination of the physical evaluation information and the auditory evaluation information.
[0173] Optionally, see Figure 11 At step S530 , a braking performance evaluation result is obtained based on the physical evaluation information and the auditory evaluation information, including:
[0174] S531, creating a braking performance evaluation table; the braking performance evaluation table includes a plurality of body-sensory evaluation information, a plurality of auditory evaluation information and corresponding braking performance evaluation results.
[0175] It can be understood that the braking performance evaluation result is a score obtained by integrating the physical evaluation information and the auditory evaluation information, and is used to represent the comfort and safety of the vehicle when the disc brake 200 is braking. As shown in Table 3:
[0176] Table 3:
[0177] Physical evaluation information Braking performance evaluation results Auditory evaluation information Comfort Louder Harsh stinging Comfort Very comfortable Comfort Mild discomfort discomfort Slight pain Comfort Mild discomfort discomfort unbearable pain Mild discomfort discomfort unbearable unbearable severe pain discomfort unbearable unbearable unbearable
[0178] S532 , matching the somatosensory evaluation information and the auditory evaluation information in a braking performance evaluation table to obtain a braking performance evaluation result.
[0179] It is understood that, based on the physical and auditory evaluation information, corresponding braking performance evaluation results can be matched in the braking performance evaluation table. For example, if the physical evaluation information is "painful" and the auditory evaluation information is "loud," the braking performance evaluation is "uncomfortable." Alternatively, if the physical evaluation information is "comfortable" and the auditory evaluation information is "stinging," the braking performance evaluation is "uncomfortable."
[0180] With such a setting, by analyzing and summarizing the load status information, the braking performance evaluation result is obtained by comprehensive consideration of the physical evaluation information and the auditory evaluation information, taking into account the impact of the disc brake 200 on the load on the vehicle during braking, such as the comfort of the vehicle during the braking process of the disc brake 200, and reflecting the true performance of the disc brake 200 from multiple angles, which is conducive to accurately testing the braking performance of the disc brake 200, reducing errors in subjective judgment, and improving the accuracy and reliability of the test results, thereby deriving the improvement direction of the disc brake 200 and improving the market competitiveness of the product.
