The Analysis of H-Shape Rolling by the Finite Element Method
유한요소법에 의한 H형강 압연공정의 해석
Abstract
Shape rolling processes to produce H-section beams are numerically simulated by the simplified three-dimensional finite element method. The 2-dimensional finite element method, used for the generalized plane strain condition, is combined with the slab method. Computer simulation results of the 19-passes in H-section beam rolling in practice include the grid distortions, the cross-sectional area changes, the roll separating forces, and the roll torques. Also, the amount of side spread can be found during the multi-pass rolling simulations. The finite element mesh system is remeshed with I-DEAS whenever the billet distorts severely. This study would contribute to CAD/CAM of shape rolling process through the optimal roll pass schedule.
본 연구에서는 앞서 개발된 3차원 강소성 유한요소법을 이용하여 H-형강 압연 공정을 해석하여 그 타당성을 검토하고 이를 실제의 공정 설계에 이용할 수 있도록 하였다.
