The Fuel-efficient Vehicle Frame for Energy Saving Competition Design and Analysis Based on ABAQUS

Abstract

Non-load-bearing body, with an independent frame, is subject to gravity load provided by itself and load-bearing components, and also subject to excitation load from the road and engine, etc. Therefore, the rigidity and strength of the frame must be ensured in the frame design, so the welding strength in the frame fabrication process is extremely important. In this paper, the basic characteristics of the frame are analyzed by using finite element technology, and the welding displacement, stress, and strain of the frame are studied in detail. The main research contents are as follows:The thesis takes the frame of energy-saving racing car as the research object. According to the design requirements of the official committee, firstly, the 3D model software is used to design the geometric model of the racing car and rationalize the spatial layout of the frame. Secondly, the finite element model of the frame of the energy-saving racing car is established by Abaqus software, and through the process of parameter sett and load application, the stress, deformation, and modal performance of the frame under each working condition are derived. Finally, the structural parameters of the frame are compared to see whether the safety factor is achieved, so as to conclude whether the frame is qualified and whether it meets the lightweight design requirements of the racing car.
