In recent years, products that make use of integrated safety that use the environmental data to optimize occupant restraints have been on the market. Pre-safe system in the integrated safety category is an adaptive and smart protection system that utilizes the occupant information and the monitoring information on the accident prediction. These pre-safe systems need the proper algorithm corresponding to the crash scenario for the crash unavoidable state. Due to the crash scenario categories for the real world accidents is quite various, the development of the algorithm and the occupant protection system to reduce the injury is quite complex and costly. For this reason, a development process for pre-safe related integrated safety systems demands new tools based on the biomechanics to help design and assessment. The virtual development and assessment process with a viewpoint on the efficiency of the restraint development has been developed.

Shape optimization is one of methods to reduce the vehicle weight, however the method is not used widely because the definition method of shape basis vector is too difficult. In this study, shape optimization and newly shaped FE model generation with morphing technique is investigated. First the advantage and disadvantage have been compared between commercial software, Hyper Morph and DEP Morpher. Second, morphing technique is applied to several automotive components. The research results show that newly shaped FE model generation with morphing technique is successful and very efficient to reduce the time of product development.
