The vehicle design for crashworthiness and safety has become increasingly complex in recent years. Besides the safety regulations for various markets, customer’s expectation for vehicle safety has been increased due to an information publication such as US or EURO new car assessment programs (NCAP). Due to the nature of offset crash test, it’s not easy to replace by sled test. One of good ways is a simulation to see a safety performance of a vehicle and dummy injury. This paper proposed a methodology to predict safety performance and dummy injury during offset crash.

In RSM, we deploy the performance target for the occupant safety in early stage of a vehicle development. And we set a target performance for each component in order to achieve it. But the current targets are not enough to represent the occupant safety performance. Sometime, even tough all components meet the target performance, the occupant is not safe. Thus we need new technical criteria to overcome the problem above. The purpose of this study is to develop the new technical criteria for the full-wrap crash including the package, restraint system and vehicle deformation performance. By new criteria, we can predict the vehicle deformation performance more precisely and review the package performance in terms of the occupant safety before the physical test. After physical test, we can estimate the performance of restraint system and vehicle deformation.

The vehicle design environment from a crash worthiness and safety perspective has become increasingly complex in recent years. In order to meet all the legal requirements and safety targets, an approach of using physical testing solely has serious problems associated with it. Due to the prohibitive nature of vehicle protypes and limited availability during engineering development, other tools such as CAE have become popular. Occupant kinematics analysis has been widely used for the integration of safety systems such as airbag, kneebolster, seat belt, load limiter, steering column, etc. because occupant kinematics analysis has the advantage of the shorter analysis time. This paper will discuss the modeling technique to obtain the Force-Displacement Characteristic curve of vehicle interior and restraint system with the component test or analysis in order to build a high quality occupant analysis model.

Vehicle safety has been extended to pedestrian protection on road from passenger protection in a vehicle. According to pedestrian protection regulation in Europe and Japan, head and leg injury must not exceed the limitations in the defined test conditions for the protection of pedestrians and other vulnerable road users at a collision with vehicle, but it is difficult to evaluate the performance of pedestrian protection in both Europe and Japan regulation because each regulation has different test conditions such as dummy, impact area, impact speed, impact angle and so on. In this paper, it is studied the relationship between test conditions and injury for Headform-to-Bonnet Impact by investigating the analysis results of Europe/Japan Regulation and EuroNCAP.
