Analysis Of The Movement Suspension Of Light Bus And Simulation Of The Entire Vehicle Ride Comfort

It is one of the important serviceability of the vehicle that the vehicle rides comfort, its fine or not to influence to take comfortableness and safe and reliable transportation of goods passenger not merely, and is influencing full play of many kinds of serviceability of the vehicle and life-span of the department of going .It is the important component of the vehicle to suspension that will have important influence to ride comfort on the vehicle. With rapid development of the auto industry, how to improve the vehicle to ride comfort, have already become designer's very concerned problem. With the development of technology, the dynamics analysis software is applied in vehicle's design and manufacture etc.The paper summarizes the develop course of multi-body dynamics theory and the basal theory of ADAMS software, the main parts and character of ADAMS are also introduced.The article aims at Refine commercial vehicle, builds up a whole multi-body kinematics model which include chassis, suspensions, tires subsystems and etc, using virtual prototyping technique in the software ADAMS. The writer develops one software to produce random roads, and also develops the other software to evaluate vehicle ride comfort. Furthermore, the simulation of suspension frequency's measure is realized. The simulation of ride comfort under different speeds and variable roads input is also realized. Through comparing with ride comfort road test result of real vehicle under the same experiment condition, have higher precision and credibility in thinking the vehicle ride comfort after verifying this model. This offers a kind of effective modernized means for the fact that the vehicle system develops.
