Taking a car's front rail as the research object, the three-dimensional geometric model of the car's front rail was established through CATIA software. By using finite element theory and method, the finite element model of the car's front rail was established based on HyperMesh/LS-DYNA environment. The Crashworthiness Performance of the car's front rail was solved with LS-DYNA. Respectively from the beam section shape, induced slot position, depth, shape, the thickness of the beam, strengthening plate, aluminum honeycomb filling material several aspects to study on the influence on the Crashworthiness Performance of the thin-walled straight beam.
