摘要
运用软件ANSYS的弹塑性有限元理论,重点研究了冲压模间隙对板材成形性能的影响,观察分析应力、应变分布和变形网格情况并与实践对比,模拟分析结果与生产实践基本吻合。板材成形有限元法为快速有效地确定冲压模间隙,优化模具设计,降低模具设计成本和缩短模具设计周期提供了一种可实施的手段。
In this paper, the main point of this paper is research on influence of clearance of punching mould on performance of sheet metal forming by using ANSYS software. The stress-strain and deformed mesh are observed and compared with experiment. The results of sheet metal forming simulation analysis are accordant with practice. Finite element method of sheet metal forting provides practicable ways for rapidly and effectively obtaining blank-holder force and clearance of punching mould, validating rationality of mould design, lowering mould design cost and shortening design cycle.
