基于Adams-Matlab联合仿真的车辆地面相互作用研究
Vehicle and terrain interaction based on Adams-Matlab co-simulation
摘要
Abstract
A kind of construction truck model is built in Adams based on multi-body dynamic theory.The rigid and elastic wheels of tire-soil contact models are proposed based on the Bekker pressure model and the Jonasi shear soil model, and they are described in the form of S-function to enhance the calculation efficiency and simulation accuracy.Finally, the interaction of truck and soil is simulated by Adams-Matlab co-simulation to study the influence of soft terrain on the ride comfort of vehicles.The co-simulation results reveal that the terrain properties have a great influence on the ride comfort of vehicles as well as driving speed, road roughness and cargo weight.This co-simulation model is convenient for adding the factor of terrain deformation to the analysis of vehicle ride comfort.It can also be used to optimize suspension system parameters especially for off-road vehicles.关键词
