Japan was one of the leading nations of the technology developed by comparing and adjusting design which solves the problem in adjustment by designers together. Currently, mechatronics products are accounted for manufacturing market in the world. Functional failure are occurring and increasing by the difficulty of the software with the rapid complication of product function. Since the comparing and adjusting design method based on existing way is failing to keep pace with sophisticated features, in brief the occurrence of rework is the cause at downstream of the design process. Therefore, conceptual design in the upstream stage is important; the authors propose the Integrated physical simulation method, have carried out a design support by stepwise refinement of complex product design. However, the Integrated physical simulation method is performed support of software mainly. Therefore, the authors provide support for hardware by stepwise refinement physics simulations and applied to the chassis design in this paper.
