| 摘 要： | 为深入研究常用路面不平度随机模型的特性,基于Matlab仿真环境,对白噪声法、谐波叠加法、FFT法、AR/ARMA法4种模型在指定环境下的效率与结果进行了仿真分析和比较.在将4种模型拓展到多点时域模型后,对多点单轮辙模型的时延相关性、可用性和严密性以及多点双轮辙模型的轮辙相关性、合理性和波动性进行了仿真分析和比较.结合模型适用范围与扩展应用等方面的比较,给出了4种模型应用特性的综合评价结果.完善了多点时域模型的建模方法和体系,得到的评价结果,为车辆优化和设计、路面不平度和谱分析、道路数据库建立以及人车路大系统分析等方向的科研工作者选择模型提供了理论依据.

| Abstract: | To study the characteristics of common time domain models of road irregularity excitation,four types of single-point time domain models of road irregularity excitation,namely white noise filtering,harmony superposition,FFT and AR/ARMA method were analyzed.The efficiency and simulation results of these four methods in MATLAB environment were analyzed and compared. All these models were developed and applied to the multi-point time domain model in order to investigate the time-delay correlation,availability a... |
