基于电子表单的圆柱形壳体结构参数化设计

Parametric Design of Cylinder Shell Based on Spreadsheet

针对水下航行器研制中存在的设计周期冗长现象,提出了一种结构设计的新思路,以自主式水下航行器(AUV)圆柱段壳体结构优化设计为例,利用电子表单使UG的建模功能与MATLAB科学运算功能得到有效的结合,完成了对壳体结构的优化设计及模型更新,重点说明了如何利用电子表单在MATLAB与UG之间进行数据通信,实现了参数化结构的优化设计。研究结果表明,该方法能极大地缩短结构设计周期,减少由于零件尺寸变化带给工程师设计上的工作量,也使得产品的结构设计系列化成为可能。

To shorten design period of autonomous underwater vehicle（AUV）,this paper presents a new approach by taking optimization design of an AUV cylinder shell construction as an example.The UG′s modeling ability and the MATLAB′s scientific computing function are combined effectively by virtue of the spreadsheet,and the 3D model of cylinder shell is updated according to the optimization result.This paper highlights the way of data transmission between MATLAB and UG via spreadsheet.This study shows that the present method can greatly shorten the structure design period,reduce the engineers＇ workload,and make it possible to serialize the product structure design.
