【 摘 要 】

References(15)This paper describes a newly developed optimization system based on a new Finite Element Sensitivity Analysis (FESA) of mechanical structures with coupled problems concerning heat conduction and stress analysis. In this system, variation in a material property, for example heat conductivity, is considered as a structural change because changing a material property locally or partially is difficult. Like FESA, this system requires just one calculation and then offers efficient designing products. The effectiveness of the system was verified by results showing that optimizations of structural design were given efficiently when the system was applied to the design of actual industry products: a turbine blade and a cooling jacket of computer modules.
