Abstract:
Ls-Dyna software which is commonly applied to simulate basic physics problems has been developed by Livermore Software Technology Corporation (LSTC). With the ability of solving nonlinear dynamics problems, Ls-Dyna has been widely used in the fields of the automobile industry, shipbuilding, construction, military, ... This paper presents the research results of using LS-DYNA software to build a finite element modeling and analyze the safety features of the passenger car head structure when colliding with bridge railings. To enhance safety and reduce passenger injury, an energy-absorbing device is designed and installed to the front lower bumper of the vehicle. Simulation results show that when the collision absorber is mounted, the vehicle acceleration caused by a collision at the center of gravity of the vehicle as well as the kinetic energy of the vehicle at the end of the simulation decreases.
