基于CATIA对海底门的参数化设计

本文以海底门为对象，针对其三维模型应用场景单一，调整繁琐等问题，基于CATIA知识工程，对海底门相关结构进行参数化设计，获得了能够适用于海底门各种舱体，并可以提供给用户自定义选择的海底门工程模板。该工程模板可以根据用户提供的海水门舱体，自动把海水短管、法兰基座、肘板、格栅、防海生物装置以及吹洗管一同复现在输入的舱体上。用户可以依据实际情况自由的修改海水流量、海水流速、法兰基座类型与公称压力、格栅类型与规格以及流通面积比等参数。除此之外，用户可以自定义海水门各个结构的安装位置，并可以对肘板进行旋转。

Parametric design of submarine door based on CATIA

This paper takes the submarine door as the object, and solves the problem of single application and adjustment of cumbersome problems. Based on CATIA knowledge engineering EKL development technology, the parametric design of the submarine door related structure is carried out. A subsea door engineering template is obtained that can be applied to various types of subsea doors and can be customized to the user.The project template can automatically restore the seawater short pipe, the flange base, the bracket, the grille, the anti-sea biological device and the purge pipe to the input cabin according to the seawater door cabin provided by the user. Users can freely modify seawater flow, seawater flow rate, flange base type and nominal pressure, grille type and specification, and flow area ratio according to actual conditions. In addition, the user can customize the installation position of each structure of the seawater door and rotate the bracket.
