Embodiment 1
[0042] see figure 1 As shown, a durability test system for a seat adjuster, including a test platform, the test platform communication connection has a state detection module, a user analysis module and a comprehensive analysis module;
[0043] The state detection module is used to detect and analyze the working state of the seat adjuster, and analyze the state of the seat adjuster through mechanical tests such as noise and stuttering. The specific working state detection and analysis process includes:
[0044] Set the detection cycle after the seat adjuster leaves the factory, divide the detection cycle into detection period i, i=1, 2,...,n, n is a positive integer, the duration of each detection period i is L1 days, and L1 is the quantity Constant, obtain the noise value generated when the seat adjuster is used in the detection period i and mark it as ZSi, the noise value is directly obtained by the sound sensor, and the sound sensor has a built-in capacitive electret microp...
Embodiment 2
[0050] see figure 2 As shown, the test platform is also connected with a test module for communication, and the test module is used to test and analyze the accuracy of the durability analysis results: the test value JY is obtained through the formula JY=a×ZB, where a is a proportional coefficient, and 1.2≤a≤ 1.25; Select a point on the durable ray as the inspection point, the ordinate value of the inspection point is the inspection value, obtain the abscissa of the inspection point and mark it as the inspection time, and mark the difference between the inspection time and the delivery time as the inspection duration JS, Real-time monitoring of the state performance value of the seat adjuster, when the state performance value of the seat adjuster reaches the inspection value, mark the difference between the current time and the factory time as the analysis time FS, and use the formula JM=|JS-FS | / JS obtains the inspection coefficient JM, and compares the inspection coefficient...
Embodiment 3
[0053] see image 3 As shown, the durability performance test of a seat adjuster includes the following steps:
[0054] Step 1: Set the detection cycle after the seat adjuster leaves the factory, and use the state detection module to detect and analyze the working state of the seat adjuster within the detection cycle and obtain the state performance value;
[0055] Step 2: Use the weight analysis unit to detect and analyze the user's weight and divide the detection period into a floating period and a fixed period, and judge the pressure performance value of the detection cycle through the comparison result of the floating ratio and the floating threshold;
[0056] Step 3: Use the frequency analysis module to detect and analyze the use frequency of the seat adjuster and obtain the frequency performance value of the detection cycle;
[0057] Step 4: The comprehensive analysis module performs durability analysis on the received state performance value ZB, pressure performance va...
