The front bumper is the main energy-absorbing component in the frontal impact, which, to a large ex- tent, determines the crashworthiness and safety of a vehicle. Based on the large deformation and nonlinear con- tact of front bumper in the process of vehicle collision, the finite element model of front bumper (including bumper, energy-absorbing box and longitudinal beam) colliding with the rigid wall were established. The piece- wise linear plastic material constitutive model and explicit dynamic finite element method were adopted to dy- namically simulate the process of collision and the deformation, energy changes and impact force curve of bumper, energy-absorbing box and longitudinal beam were obtained. The simulation results are in good agree- ment with the experimental results, which verifies the correctness of the finite element model. The research re- sults show that the inducing structure of slot type is easier to induce the fold deformation of longitudinal beam than that of the inducing structure of box type, and the impact force curve fluctuates with the fold deformation of longitudinal beam.
