摘要
本文通过控制变量法测量多辆车在不同条件下的车轮拖滞力矩,然后对多组测量数据进行处理分析,得出各干扰因素对测量车轮拖滞力矩的影响程度,据此制定出相对科学的车轮拖滞力矩测量方法,提高了测量数据的准确性。
In this paper,the control variate method is used to measure the wheel hysteresis torque of dozens of cars under different conditions,and then several sets of measurement data are processed and analyzed to obtain the influence degree of each interference factor on the measurement of wheel hysteresis torque.Based on this,a relatively scientific measurement method of wheel hysteresis torque is developed to improve the accuracy of the measurement datas.
