Front Crash

Front crash has high probability in tranfic accident, and the front energy absorption part plays a very important role during the crash and is the key point to protect the safety of the occupant. The whole vehicle front crash is simulated in software LS-DYNA. This paper fix out the key steps and parameters in FEMB, and make good advise for finite anlysis. Finite anlysis is used in this paper to study motionstate of the vehicle and the energy absorption. Due to the anlysis, we find out that the front longitudinal beam is the most important component in the crash.

Front Crash

Traffic accidents cause to a large quantity of personnel casualty and economic loss every year. The safety in vehicle crash has been one of important criterions in vehicle design. In this study a three-dimensional finite element model was established and the front crash process of car bodywork was analyzed. The simulation results show that the structure design of car bodywork is reasonable and of safety for the passengers. The investigation of this study not only validates the rationality of the car bodywork design but also provides a detailed numerical simulation model for further investigation as well as improvement and optimization of the car bodywork structure.

Front Crash

To study the injury index to driver in front crash, this article uses the MADYMO software to establish the driver constraint system model which including car bodies, safety belts and 50% dummy for impact simulation. The simulation values are close to test ones after contrasted with the vehicle impact test. The influence of design parameters including the D-ring friction coefficient of seat belt, airbag strap and steering column on driver HIC, T3MS, THPC are researched by this model. The results show that: The smaller D-ring friction and a longer airbag strap length and steering column crushing can effectively improve the driver safety.
