摘　　要：在有限元法的自动前处理工作基础上，对回转体非线性边界元提出了网格自动生成的改进连续超限插值法。文中详细讨论了改进的连续超限插值函数的构造、网格疏密控制和区域大小的控制方法，针对机械结构中几种典型的回转体给出了边界元网格划分的算例。This paper proposed on the modified continuous transfinite interpolation method for the automaticgrid generation of axisymmetric BEM in terms of previous automatic mesh generation work in FEM. The construc-tion of modified continuous transfinite interpolation function and the method of controlling the space of grid and thesize of mesh were discussed in details. The examples of mesh generation for several axisymmetric bodies were givenfinally.
