Ride Comfort Simulation under Random Road Based on Multi-Body Dynamics

The car ride is important to use performance affecting the performance of a wide variety of used vehicles. Suspension is an important part of the automobile, suspension ride on vehicles which have had a significant impact. With the rapid development of the automotive industry, how to improve vehicle ride, has become one of the designers are very concerned about the problem. In addition, dynamic analysis software in the automotive design, manufacturing, etc. Paper provides an overview of the main module UG, and takes advantage of UG has established a solid model automobile suspension. Describes the theoretical basis of ADAMS, and describes the main module ADAMS and ADAMS software features For Fiat automobile company. For the car, with the aid of multi body dynamics analysis software ADAMS, the whole vehicle model is established. And at a different level pavement, different speed down random input of ride comfort. In the model on the basis of properly developed automobile suspension parameters on the impact of automobile ride.
