RESEARCH ON LIGHTWEIGHT OF AUTO-BODY MATERIAL BASED ON CRASHWORTHINESS SIMULATION

Abstract

Abstract: Finite element theory is applied and the new style passenger car is used as the prototype, when using high strength steel and aluminum alloy to lighten auto-body, the total weight can be reduced 9.31 kg, 53.10 kg and the lightweight effect is 11.31%, 64.50%. Based on carshworthiness simulation according to CMVDR294, compared the deformation of entire car, the crash force to the rigid wall, velocities, accelerations, and energy-absorbing ability of main parts, the results of crashworthiness simulation verified the feasibility of the proposed method.

Key words: High strength steel, Aluminum alloy, Auto-body lightweight, Crashworthiness, Finite element method
