Title The frame structure design of a certain type electric vehicle
Abstract
This paper is a study of a certain type of tourist cars electric vehicle frame, the main task of this paper is to design the frame for the electric vehicle based on the structure and performance of the electric vehicle. The main contents of this paper is to learn the structure and performance requirements clearly, understand the basic structural parameters, and then modeling for the electric vehicle frame structure using the CATIA 3D modeling software，based on a given type of electric car. After the frame model simplification, mesh for the simplified electric vehicle frame model and establish the finite element model of the frame by HyperMesh. Take modal analysis and static analysis for the electric vehicle using HyperWorks and determine that the design of the electric vehicle frame is reasonable through the results of analysis. Therefore, three-dimensional model is correct, and then draw the two-dimensional drawing for the frame.
