摘要：

针对大型卷板机上辊挠曲变形的补偿难题，利用ANSYS有限元优化方法，对某21 m大型船用卷板机的上辊支承辊的数量、位置及施加载荷的分布进行了合理优化，进而提出了挠度补偿措施。结合有限元分析方法分别得到了上辊和上梁在优化载荷作用下和整体模型在工作载荷作用下的挠曲变形，并对预补偿后的情况进行了分析，补偿后上辊的最大挠度是0.71 mm，几乎能使上辊趋于水平，结果满足卷板机上辊挠曲变形的补偿要求。

In order to solve the problem of deflection compensation of upper roller for large marine bending machine, using FEA optimization method based on ANSYS, the amount, locations and the imposed loads of bearing rollers of 21 m large marine bending machine were optimized reasonably and the deflection compensation measure was proposed. The deflection of the upper roller and beam in optimizing loads and overall role model in the working load were obtained through finite element analysis method. After compensation, the maximum deflection is 0.71 mm, the upper roller almost tends to be level . The result of precompensation by finite element analysis method shows that it is feasible for deflection compensation of upper roller for large marine bending machine.
