摘要
建立以板壳单元为基本单元的机架有限元计算模型,利用有限元分析软件ANSYS对其进行了随机振动分析,找出机架的危险部位,为产品改型设计提供依据。
In this paper,the FEA modal of the vehicle frame is established by taking shell unit as a basic unit .The analysis of random vibration is made by using ANSYS feas .The weak part is pointed out . The basis is also provided for three-wheel vehicle design and improvement.
