Heavy-Duty Car Multi-Body Dynamics Simulation and Optimization Research

TIn this paper, according to the structure characteristics and using characteristics of heavy duty truck, we use the principle of vehicle dynamics and simulation analysis method to deeply study the dynamic characteristics of heavy duty truck. And we also use the heavy duty model to carry on the optimization simulation and experimental validation for riding smoothness and handling stability. So as to guide the development and design of heavy duty truck, to get the purpose of control the dynamic performance and shorten the development cycle.
