摘要
通过辊弯拱型波纹板的回弹公式计算和有限元模拟计算 ,探讨了辊弯拱型波纹板的回弹问题。研究得出 ,辊弯拱型波纹板的回弹过程是一个应力释放过程 ,回弹后的最大变形量降低 ;带有侧边板的拱型波纹板回弹前后曲率半径变化不大 ,而无侧边板的拱型波纹板曲率半径变化较大 ;理论曲率半径值与实测结果基本符合。
According to the rebound calculation formulas and the ANSYS finite element analysis,the thesis researched the rebound problem of the corrugated arch sheet made by roll bending The results show that the rebound process of the corrugated arch sheet is the process of releasing stress,the radius of curvature of the corrugated arch sheet with side board has changed during 7～10mm,and the theoretical radius of curvature is matched the actual
