| Abstract: | The effects of temperature field and pressure field on residual stress and deformation of injection molded parts was studied by FEM.The computation of temperature filed,pressure filed in molding process and deformation based on thermoelastic theories were discussed mostly.The factors that affected motorcycle tail cup warpage,such as mould temperature were analyzed,and the cause of warpage and the improving measures for the injection product were also put forward. |
