FULL-FRONTAL COLLISION SIMULATIONS AND ANALYSES OF TUBULAR SPACE FRAME BODYWORK FOR SEDAN CAR

摘要

Using CAE tools based on nonlinear finite element methods, full-frontal collision dynamic simulation and analysis of a sedan car body with 3D tubular load bearing frame are tentatively carried out. Time histories of the main collisional parameters are presented, improvements of the frame are partially made according to simulation results. Collisional simulation of the tubular frame alone indicates that, such new type of bodywork for sedan car is of good potentialities to meet the collision safety regulations.
