Abstract

Firstly, the finite element model of a certain car is established, and then according to the regulations and standards of FMVSS 216a's "top compressive strength of passenger car", the test simulation analysis for ceiling compressive strength is presented. By comparing the energy curve, the accuracy of the simulation model is verified. A large number of simulation experiments on key parts of car body, such as, the upper and lower ends of the A-pillar, B- pillar and roof beam, are conducted in this paper. The goal is to do the research on the relationship between the thicknesses of these key parts and the compressive strength of the roof. According to the result of orthogonal experiment analysis, it is concluded that the influence of the key parts is Upper of B-pillar>Lower of A-pillar>Beam before the wind>Roof beam>Upper of A-pillar>Lower of B-pillar; Which play a major role in key parts is the B-pillar side. The optimization for key parts of car body is achieved, obtaining the best optimization program, so that compressive strength and safety margin of the roof are improved.
