基于MSC.Patran/Nastran的结构优化程序系统的二次开发

The Secondary Development of Structural Optimization Program System Based on MSC.Patran/Nastran

尽管Patran/Nastran软件具有强大的工程解决能力和广泛的通用性,但在复杂的工程结构优化领域,由于缺乏针对性而使其应用性下降。采用该软件提供的二次开发工具PCL,基于Patran平台,将有限元软件Nastran和一些专用算法结合,开发了一套结构优化设计系统。该系统可以使设计过程高度自动化,并通过典型算例验证了它的正确性和高效性。

Although Patran/Nastran software is very versatile and has big capacity to satisfy the engineering applications, it is not special for the some complicated problems about structural optimization. Therefore, the secondary development tool, PCL, is provided by the software. Based on PCL and Patran platform, a system for structural optimization, which automatizes design process highly, is realized by using commercial software Nastran and some expert algorithm together. Several typical numerical examples are given to verify the correctness and excellent efficiency of this system.
