摘要
在整车仿真分析中,钢板弹簧模型的建立一直是个难点,对于三轮汽车的整车仿真来说更是如此。为了建立比较精确的钢板弹簧模型,本文根据三轮汽车钢板弹簧的结构及受载特点,以多柔体系统动力学理论为基础,利用UG、Hyperworks与Adams建立了钢板弹簧的多柔体模型,并对其特性进行了仿真研究,然后将仿真结果与试验结果进行对比,验证了模型的正确性。
In simulation analysis of whole vehicle,modeling of leaf spring is always difficult,especially for three-wheelers.To establish relatively accurate leaf spring model,in this paper,a flexible multibody model of leaf spring is established with UG,Hyperworks and Adamsbased based on flexible multibody dynamics theory,simulation study is carried out to its characteristics.Then the simulation results are compared with the test results,which verified the correctness of the model.
