Simulation of General 3D Virtual Stochastic Road Model
In order to provide the research of virtual prototype a complex 3-D virtual road environment based on a new method，a 3-D Pseudo Excitation Method stochastic road model was established based on the single-point Pseudo Excitation Method model, and then the simulation result was gained by Matlab.What’s more，based on the theory of triangle network，a general 3-D virtual road model with the arithmetic of nodes and elements was created.Then a specified 3-D virtual road file was imported into Adams to form the 3-D virtua1 road. Finally, a C-level virtual road was generated for the riding performance simulation of virtual vehicle.By comparing the simulation result with the GB／T 13441-92，the virtual vehicle’s reasonable time under the ride performance requirement was obtained.
