摘要

在制造设计中,网格生成在装配和有限元方程求解中是一个耗时且昂贵的过程。实体模型到有限元数据的转换也很耗时,并且经常引入许多歧义。本文提出了一种新的平面应力分析的无网格方法。在形状函数的生成中采用了移动最小二乘逼近。用该方法得到的结果与解析解和有限元法的结果进行了比较。与有限元近似相比,该方法计算量小,计算精度高。

Intensification of the Subsisting Methodology to Enhance DFM without Discretization
In the design for manufacturing, mesh generation is a time-consuming and expensive process in the assembly and solution of the finite element equations. The conversion of solid models to finite element data is also time-consuming and often introduces numerous ambiguities. In this study, a new mesh-less method has been proposed for analyzing the plane stress problems. The Moving Least Squares (MLS) approximation has been used in generating the shape function. The results obtained by the proposed method have been compared with the analytical solution and finite element method (FEM) results. The proposed method gives more accurate results than the finite element approximation, with less computational effort.
