    摘要:

    在正弦波疊加模型的基礎(chǔ)上進(jìn)行了隨機(jī)路面譜的計(jì)算機(jī)模擬,。從空間路面頻率譜出發(fā)給出了模擬隨機(jī)路面譜的方法,。利用Matlab軟件編制了生成任意等級(jí)三維隨機(jī)路面譜的程序。最后結(jié)合多體動(dòng)力學(xué)仿真軟件ADAMS的虛擬樣機(jī)技術(shù)對(duì)生成的隨機(jī)路面譜進(jìn)行了分析和討論,。結(jié)果表明,，該隨機(jī)路面譜的計(jì)算機(jī)模擬能夠更便捷的結(jié)合相關(guān)的軟件進(jìn)行汽車性能的分析和評(píng)價(jià),。

    Abstract:

    The computer simulation on stochastic road irregularities is performed based on the sinusoid superposition method. The procedure for deriving the stochastic road irregularities is given with the application of space frequency domain road model. The stochastic road irregularities are generated by the program coded by Matlab software. Finally, the stochastic road irregularities are carried out by exporting it to the virtual prototype technique software ADAMS for evaluating the performance of vehicles. It is shown from the results that the process for analyzing and evaluating the characteristics of vehicles becomes more convenient with the application of the generated stochastic road irregularities.
