摘要
采用双轨路形计,对4种试验场路面谱进行了测试,并对测试结果数据进行了功率谱密度和路谱等级分析.分析和仿真应用结果表明,所得路面谱和路谱等级,可以应用于车辆动力学仿真及试验室的道路模拟台架试验.
The road spectrum of four kinds of test sites was tested by using dual track shape meter,and the power spectral density and road spectrum grade of the test data were analyzed.The analysis and simulation results show that the obtained road spectrum and road spectrm grade can be applied to vehicle dynamics simulation and road simulation bench test in laborary.
