摘要
汽车车架是整个汽车的安装载体,不仅要支撑固定车上各个部件,还要承受着来自道路的各种复杂载荷的作用,是整车可靠性和使用寿命的重要保证。因而,车架的强度和刚度在汽车总体设计中显得非常重要。其中,三轮车车架是一个多自由度弹性振动系统,稳定性一般比四轮车差,对车架的强度和刚度要求更高。本文以我校参加本田节能竞技大赛的三轮赛车车架为研究对象,按照一定的模型简化原则,以有限元分析方法为基础,利用ANSYS软件建立节能赛车车架有限元模型。为了在简化计算的同时获得可靠的计算结果,单元类型采用梁单元BEAM189。同时,文章中对赛车实车静止状态进行了受力分析。
As the base of a vehicle, the frame, on which most of the parts and components are assembled, supports all kinds of complicated loads coming from the road. So the intensity and the rigidity of the frame are of great significance in the vehicle＇s design. Because the frame of three-wheel vehicles is an elastic vibration system with several degrees of freedom, its stability is worse than four-wheel vehicles＇. Therefore, it requests the intensity and the rigidity much higher. In this paper, the research object is the frame of Honda energy-saving vehicle. According to the rules to simplify a model and the finite element method, software ANSYS is applied to build the FEM model of the frame. In order to simplify the calculation and ensure the reliability of calculation results, BEAM189 is selected as based element. And static force will be analyzed in this paper.
