Research on Time Series Modeling Method of 3D Stochastic Road

基于单自变量时序道路模拟原理与方法的拓展,用双自变量时序模型对三维随机路面进行刻画。介绍了时序模型分类、模拟原理及其在道路模拟中的主要应用;对三维路面建模进行分析,给出了三维路面时序模型的建模过程和实施步骤,所构建的三维时序模型方法可以用于任意的平稳随机道路的重构;通过算例研究对所用方法进行了验证。

Based on the previous work on the road time series model,a further development toward the 3D road simulation by using double auto-variable time series method was made.The basic principle of time series model was introduced and then the present application to the road simulation and the main models were summed.Through the discussion about the digital feature of the arbitrary roads,an innovative simulation method of 3D stochastic road surface by using double auto-variable time series was proposed and the application process and the flow were analyzed.＇
