This paper describes the development of three interior safety parts, airbag housing, steering wheel and seat component from preliminary design to commercial mass production. For all the parts the development process includes loading characterization, material selection and testing, static and dynamic nonlinear finite element analyses, prototype diecasting production, X-ray examination and static, impact and fatigue acceptance tests for reliable parts. The design optimization is the considered to reduce weight as well as price production. The optimization results are discussed as a function of diecasting parameters, mechanical properties of specimens that were taken from different critical part zones, X-rays and fatigue tests. Development and design recommendations are presented based on the above experience and study.
