Abstract

Vehicle’s suspension is an important component to ensure ride comfort, which is called the soul of chassis design. The performance of suspension directly affects the vehicle’s ride comfort and handling stability. The design of the vehicle’s suspension system must fulfill the demand of ride comfort and handling stability. Meanwhile, the suspension, the transmission connecting device between the frame (or body) and the axle (or wheels), is to ensure the safety of driving. It is also one of the indicators to measure the quality of modern automobiles. In the article, it establishes a model of the vehicle nonlinear system for suspension with two degrees of freedom. It uses statistic linearization method to translate the random vibration issue in nonlinear system to that in linear system. Besides, a simulation study is conducted and real cars are tested. The result shows that the suspension’s nonlinearity can not be overlooked. Only when the modeling of ride comfort takes account of the suspension’s nonlinearity, will the vehicle’s ride comfort can be predicted and researched more accurately.
