Abstract： To meet the requirements of rapid optimization and iteration in passive safety simulation of automobiles，the method of intercepting sub models from large model is adopted in the development of automotive architecture platforms to reduce computational complexity，accelerate computational sped， and compensate for the low eficiency of explicit solutions. The sub model optimization method can effctively improve the effciency of collsion simulation optimization，greatly shorten the development cycle，and improve the level of optimization design.
