摘　　要：介绍了纸浆模塑衬垫特点及其设计的现状。选用UG软件对桶形结构单元建模,使用Nastran软件对其结构进行有限元的仿真模拟分析。分析得出:在不同载荷作用下,该单元结构在拔模斜度为3°时抗压强度最好,最大变形最小;当拔模斜度一定时,缓冲高度与受力面直径的比值,与该结构单元抗压强度之间未呈现规律的线性关系。Introduced the characteristics of paper pulp molding pads and the design status.Used UG software to modeling of the cylinder structure,and used Nastran software to make a finite element simulation analysis on its structure.It shows that： with different loading action,such constitutional unit had the best compression strength when the pattern draft is 3°,and the deformation is minimum;when the pattern draft is fixed,the change of the ratio between buffer height and the stress surface diameter,which shows no linear relation with the compression strength of the constitutional unit.
