| 摘 要： | 装配体在工作时应视为一个整体,其受力分析与单个零部件的分析不同,需要考虑零部件之间连接部位的受力分析。针对框架类装配体的特点,结合装配体零部件之间的连接关系,提出一种装配体自然网格生成算法,并在CAA平台基础上实现了这种自然网格单元的生成,从而得到装配体的骨架模型,即有限元分析模型。实践证明:该方法在框架类装配体模型的有限元分析中是切实可行的。

| Abstract: | Parts of an assembly naturally constitute a mesh model. As a whole in work, the force analysis of the assembly is quite different from that of a single part where the connections among parts are considered. In view of the features of the framework assemblies and considering the connecting relationships between different parts, this paper presents a formation algorithm of natural mesh for an assembly and implements it on the CAA-based platform to obtain a skeleton model, namely the finite element model of the assembly. Practices show that the proposed method is valid and effective in the analysis of framework assembly models. |
