Research on the simulation of vehicle ride comfort with random road inputs based on ADAMS/view

The paper studies on the characteristics and generation process of all kinds of roads, then a program is developed for generating random road by VB software. According to the simulation requirement, a random B-road is generated and used for the vehicle ride comfort simulation. Another program is developed based on FlexPro which is data-processing software, according to the “ Vehicle vibration-Describing method for raid surface irregularity”. Using the program to deal with ride comfort data between simulation and experiment, the result of handling is that the difference between the simulation and experiment is 2.57%. So the model used above has good validity and feasibility, and a new way is opened up to research on vehicle ride comfort with random road inputs.
