摘要
车架作为汽车的主要承载部件,其在移动时所受的载荷十分复杂,其强度刚度及稳定性的变化直接影响着整个行车的安全性和舒适性.车架设计的重点之一,就是在保证车架的力学强度,刚度和动力学稳定性的基础上,尽可能地把重量降到最轻,设计得更合理,并且尽可能地减少车架的过渡部分残余应力集中.本论文 ansys分析为核心,在对江淮货车车架进行建模,对其进行满载弯曲,紧急制动,紧急转向等常见工作情况的应力及变形进行有限元分析,实现对整个车架进行轻量化和参数化设计.
Abstract
As the main bearing part of the car,the load of the frame is very complicated when it moves,and the change of its strength stiffness and stability directly affects the safety and comfort of the whole driving.One of the key points of frame design is to reduce the weight as much as possible to the lightest,more reasonable de-sign,and reduce the residual stress concentration of the transition part of the frame as much as possible on the basis of ensuring the mechanical strength,stiffness and dynamic stability of the frame.In this paper,ansys anal-ysis as the core,in the Jianghuai truck frame modeling,load bending,emergency braking,emergency steering and other common working conditions of stress and deformation of the finite element analysis,to achieve light-weight and parametric design of the entire frame.
