Finite Element Method on Die Deformation and Elastic Spring-Back Analysis for Product of Helical Gear

헬리컬 기어의 금형변형 및 탄성회복에 대한 유한요소해석

The elastic stress analysis of the die for helical gear forging has been calculated by using the nodal force at the final stage obtained from the rigid-plastic finite element analysis. In order to obtain more precise gear products. the elastic analysis of the die after release of punch and the elastic spring-back analysis of product after ejection have been performed and the final dimension of the computational product has been in good agreement with that of the experimental product.
