Open publisher page 0 citations

Abstract

Crashworthiness depends on the energy absorption character of the thin-walled structure in the vehicle.Based on the non-linear finite element software—ANSYS/LS-DYNA,several key factors have been analysed in the model-building process,and it creatively analyzes the feasibility in the surface of thin-walled structure with energy-absorption holes.And the mechanical characteristics analysis of the bumper is carried out with the optimal simulation model.
