Element model generation method with geometric distribution errors

In this study, a novel mesh model with geometrically distributed errors was developed. The product surface geometric distribution error is directly attached to the element nodes of the product ideal element model using the error surface reconstruction method and the replacement algorithm of the element node vector height based on the product’s point cloud data. The model generation module was created as a secondary development module and integrated into the CAE software.

本研究开发了一种带有几何分布误差的新型网格模型。基于产品点云数据，本研究通过误差曲面重构方法与单元节点矢量高度替换算法，将产品表面几何分布误差直接附加至产品理想单元模型的单元节点。本研究将该模型生成模块开发为二次开发模块，并集成至CAE（Computer Aided Engineering）软件中。
