To improve the collision safety of compatibility performance of big-size cars such as Trucks and Pickups, the installation of Secondary Energy Absorbing Structure (SEAS) in front of vehicle body is proposed. To evaluate the influence of design parameters on the impact behavior and response for the better design of SEAS, the collision phenomena between vehicle and Full Width Deformable Barrier (FWDB) has been simulated by using CAE tool Ls-Dyna. Finally, a new model of SEAS that has a better performance both in compatibility and lightweight will be proposed based on the technique of optimum design.
