| 摘 要： | 研究了基于有理函数的路面不平度时域模型. 采用Matlab/Simulink软件建立了基于有理函数的路面不平度时域模型,并进行了仿真. 求取了仿真输出的路面不平度时域数据的功率谱和均方根值. 对比国际标准化组织提出的路面分级标准,确定了正确的模型参数,验证了基于有理函数的路面不平度时域模型. 并导出仅需路面不平度系数表达的路面不平度时域模型. 此模型可方便、准确地对路面分级标准规定的路面进行仿真.

| Abstract: | Time domain model of road roughness based on rational functions is studied.Using the Matlab/Simulink program package,a time domain model of road roughness based on rational function is found and simulated.The power spectral density and root mean square of the simulation outputs are computed.Refer to the classification of road roughness by ISO,the correct parameters are obtained,and the validity of the time domain model of road roughness based on rational function is validated.A new time domain model of road... |
