- 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.
- 根据多体动力学在Adams环境中建立了某款工程车辆的模型, 以汽车地面力学中Bekker承压模型和Jonasi剪切模型为基础建立了刚性轮和弹性轮模型以模拟轮胎地面接触, 并将轮胎地面接触模型用S函数描述, 以提高仿真运行速度和计算精度.最后借助Adams-Matlab联合仿真工具, 对车辆与松软地面相互作用问题进行了仿真计算, 研究了地面特性对车辆行驶平顺性的影响.仿真计算结果表明, 同车辆行驶速度、路面不平度和载荷一样, 地面土壤力学特性对车辆行驶平顺性也有重要影响.该联合仿真模型能将地面变形因素考虑到车辆平顺性分析中, 为非公路车辆悬架优化设计提供了思路和研究基础.
