| 摘 要： | 以实际滚筒模型为分析对象,使用边界单元法(BEM)对该结构进行刚度计算和分析。通过数值算例验证了BEM的正确性和有效性,在此基础上,充分考虑实际工况,应用BEM法分析滚筒在重力作用下的自由变形,并与基于FEM的商用结构分析软件得到的结果进行对比。对比结果显示,BEM法在分析滚筒结构刚度时具有精度高、计算量小以及纯边界离散等特点,是一种应用于结构刚度分析的高效方法。

| Abstract: | A practical printing cylinder was analyzed in the aspect of structural rigidity computation through the BEM. Convergence study of the result was also performed to illustrate the validity and efficiency of the presented method. The free deformation of printing cylinder under gravity was analyzed by BEM with the practical working conditions considered. Results obtained from both of the FEM and BEM were compared. The comparison showed the advantages of BEM for practical structural analysis as boundary only discretization, lower cost of computation and high precision, which presented a new highly accurate method for printing cylinder deformation analysis. |
