根据车辆试验台试验轮/轮接触有别于线路的轮轨接触,具体分析在车辆运动稳定性试验时,试验台试验与线路试验之间的差别。本文以160km/h准高速客车为例,进行数学建模和稳定性计算分析,并通过试验以验证建模和计算方法的正确,在此基础上,进行了车辆不同悬挂参数下试验台稳定性试验结果的误差分析。 According to the wheel / rail contact of the test bed / wheel contact of the vehicle test bench different from the line, the differences between the test bench test and the circuit test are analyzed in detail during the vehicle stability test. Taking 160 km / h quasi-high-speed passenger car as an example, this paper carries out mathematical modeling and stability calculation and analysis, and through experiments to verify the correctness of the modeling and calculation methods. On this basis, the stability of the test rig under different suspension parameters of the vehicle Error Analysis of Test Results.
