ENHANCED STRUCTURE CAE SOLUTION WITH MOLDING EFFECT FOR AUTOMOTIVE PARTS

摘要

An increasing number of automotive parts are made of engineering plastic for its low cost and superior material properties. The traditional structure analysis for automotive injection-molded part is to perform CAE analysis based on the assumption of one or several isotropic materials. However, the material characteristic of plastic part is extremely dependent on molding process. The process-induced properties, such as fiber-induced anisotropic mechanical properties, might not be favorable to the structural requirement of final products. Besides, the mesh requirement for different analysis purposes might not be the same, either. In this paper, we integrate the CAE analysis of structure and injection molding through data-linking and mesh mapping. This approach shows the effects of mutually dependent analyses have been successfully examined in automotive injection-molded parts.
