CATIA环境下航空钣金产品的标准化设计

摘要

Under the CATIA aeronautic sheet metal designing environment, we have developed a set of designing parameter tables conforming to the relevant regulations in the Standards of the Ministry of Aviation Industry of PRC. We have implemented the selection of standardized parameters for design of sheet metal products in the whole designing process with the aid of the input interfaces of the designing table and the external database provided by CATIA. The parameter database we have developed contains five full text items of aeronautic standards and two related text items of national standards with high values in the airplane structure design.%在CATIA航空饭金设计环境下,开发出一套符合<中华人民共和国航空工业部部标准>中钣金结构要素相关标准规定的钣金参数设计表.通过CArllA提供的设计表输入接口和外部数据库文件输入接口,实现了钣金产品设计全过程的标准化参数选用.开发实现的表单式参数数据库包含常用的5项航空标准全文数据和2项国家标准部分相关数据.在飞机结构设计中有很高的实用价值.
