复杂随机路面激励的统一时域模型与拟合
Unified Time-domain Modeling and Fitting of Excitation in Complex Random Road Conditions
摘要
Abstract
Considering the significant complexity and randomness of road excitation,a unified expression that can ful-ly reflect the random characteristics of typical road excitation,such as stationary random excitation,non-stationary random excitation,and discrete excitation,was established.Furthermore,a unified time-domain model of the complex road excita-tion including typical road excitation and mixed road excitation was constructed.The fitting method of actual complex road excitation was proposed,and the validity of the unified time-domain model of complex road excitation and the fitting meth-od was verified by an example.The results show that the unified time-domain model of complex road excitation can describe the actual road excitation characteristics well,and can fit the actual complex road excitation signal effectively and accurately.This work has provided a necessary theoretical basis for further study of vehicle dynamic performance.关键词
