摘要
介绍了在ADAMS环境下建立扭杆梁式半独立悬架的等效多体动力学模型和柔性体-刚体模型的方法,对两种模型进行了以定位参数变化为目标的悬架动力学仿真分析,并探讨了两种建模方法的特点。同时通过试验对两种建模方法的有效性和可行性进行了验证。该文所做的工作为轿车扭杆梁式半独立悬架的建模提供了新的方法,也为进一步的整车动力学建模和仿真以及轮胎不均匀磨损的研究打下了一定的基础。
Two methods of modeling the twist beam rear suspension in ADAMS were introduced. One is equivalent dynamics of milt body model, and another is flexible-rigid body model. The dynamic character of the twist beam rear suspension was analyzed through simulating the two methods, and the difference of two methods was discussed according to the results of the simulation. Also two models were testified by the experiments. The research supplied new ways of modeling, which could be used to discover the dynamic character of suspension and uneven wear of tire.
