U型截面弯曲件失稳起皱分析

A Study of the Bending Wrinkle of U-shaped Cross-section part

对U型截面弯曲件失稳起皱问题进行了研究,通过板材成形性能实验及起皱模拟实验,对失稳起皱原因进行了分析,为类似的异型截面弯曲件起皱的预防提供了可行的实验分析方法。

The bending wrinkle of U- shaped cross-section part is studied. By uniaxial tensile test and imitation experiment , the reason why bending wrinkle is caused is analyzed. This work provides an available testing method to prevent bending wrinkle of complex-shaped cross-section part.
