Finite Elements Analysis on the Impact Absorption Behavior of Composite Vehicle Longeron

摘要：

In this paper,an experimental model was built in the nonlinear finite element software LSDYNA. A metal tube wrapped fiberglass epoxy composite outside (called composite tube for short) was impacted in its axial direction in the simulation. The key problems about building the model were discussed later. Comparing the simulation and experiment results,we proved the validity of the model. Furthermore,we applied the material type of the composite tube to vehicle longeron,and carried on the simulation of automobile frontal collisions in LS-DYNA. The simulation results showed using the new type composite material could reduce the longeron weight to original 33.76% without lowering the safety.
