复杂空间曲面的参数化网格划分方法研究

The study of parametric grid generation on the complicated spacial surface

根据参数化有限元分析的要求, 提出了参数化网格划分的思想, 并详细地叙述了参数化网格划分的方法和实现途径。针对汽车覆盖件这种复杂的三维曲面这一特例, 编写了参数化网格划分的程序。最后利用该程序对某汽车公司匹卡车的第一横梁和某汽车油杯进行了网格划分, 成功地实现了网格划分的参数化。

Based on the request of the parametric finite-element analysis, the thought about parametric grid generation is brought forward, and the method along with the route realized in this paper is also describled in detailed. According to the Complicated Spacial Surface such as the auto body panel, a routine about parametric grid generation is compiled. Finally, the first beam of the Pick-Up car of an automobile company and an oil-cup are meshed parametrically succeed with this program.
