樹脂射出成形のコンピューターシミュレーションに関する研究

抄録

A package of computer programs has been developed for CAE (Computer Aided Engineering) in the injection molding of thermoplastics. It consists of mold cooling, polymer melt flow, fiber orientation, material properties, and stress analysis programs for 3-dimensional thin-walled molded parts. They are integrated by using a common geometric model and are used to predict the quality of molds and molded parts at the stage of design. This article summarizes the theory and verified results of the polymer melt flow, fiber orientation, and material properties analyses associated with rheology.
