Study Based On ADAMS Of Dynamic Characteristics Of Rolling Lobe Air Springs

Air spring is one of the key components of air suspension and widely used in the commercial vehicles and high speed passenger vehicles. In order to optimize the characteristics of air springs and built road -friendly suspension, it is important to analyze the static and dynamic characteristics of air spring.In this paper, modeling virtual product of 644N rolling lobe air spring produced by GuiZhou QianJin Rubber CO., LTD. Analyzing the static characteristic of the virtual product with the nonlinear finite element analysis software MSC.Marc. to prove the correction of the virtual product model of the air spring .Using the finite element analysis and simulation software ADAMS analyzes the dynamic characteristic of the vehicle which uses leaf spring suspension,Nishimura-air spring suspension or Krettek-air spring suspension. Contrasting the riding quality of the vehicle which uses different suspension, to get the best model of air spring.This project provides the theoretical and implemental basis for the design of road -friendly suspension and developing of air springs.
