鱼雷壳体的参数化设计技术

Parameterized Design of Torpedo Shells

本文借用有限元、成组技术及模块化设计的思想，将鱼雷壳体拆分成若干个标准设计单元，然后再将这些单元分组分类，建立各单元的参数化模型，设计时通过对这些标准设计单元的选择及几何参数的确定完成鱼雷壳体的结构设计工作，并形成整个鱼雷壳体的参数化模型。应用系统集成的工程分析软件，调整和修改壳体的几何、物理参数使设计结果达到最优。采用此方法实现鱼雷壳体的计算机辅助设计具有方法简便、设计效率高，易于实现计算机集成设计的特点，具有一定的实用价值。本文研究为复杂零件的参数化建模、参数化设计、工程分析及计算机集成设计等提供了一种新的方法和思路。

By using the thought of Finite Element Method, Group Technology and Modular Design, we divide torpedo shells into some stantard design units in the paper. Then. classify these units and build their Parameterized models. A torpedo shell can be designed by chosing the shapes and parameters of these units. At the same time. the parameterized model of the whole torpedo shell is formed automatically by the computer. With the help of the engineering analysis softwares integrated in teh design system，a optimal torpedo shell can be derived by adjusting the parameters of the shell. The research in the paper presents a new effective method for the parameterized design of complex parts.
