Pyramid Type Three-roll Bending Machine의 곡률 가공 정보 도출

초록

This study objective is determining vertical displacement of the center roller of pyramid type three-roll bending machine to produce the desired curvature plate. The model is a plate with rectangular cross-section on a three-roll bending machine. The analytical analysis for the relationship between center roller displacement and residual curvature of plate is carried out by considering geometry of process based on beam theory. Consequently, the analytical result is verified by finite element analysis using the information of center roller displacement which calculated from analytical analysis.
