摘要
在MATLAB/Simulink平台下利用滤波白噪声生成法重构时域路面不平度模型,模拟输出路面不平度曲线,采集模拟生成的路面不平度幅值信号,用周期法生成路面不平度仿真模型功率谱密度(PSD),并与国际标准路面不平度功率谱进行比较,分析了仿真误差。
The linear filter method is employed to establish the time-domain pavement roughness model in terms of different pavement conditions and vehicle speeds. The pavement roughness curve was plotted in MATLAB/Simulink. The power spectral density of the pavement roughness model is generated by period method when analog signals are gathered. The simulation precision is obtained by comparing the simulation result with the international standard of PSD.
