摘要
为了解决飞机公差设计计算机化的问题,探讨了飞机公差模型的建模技术;在UG(UniGraphics)平台上采用UG的二次开发技术和VC++,开发了计算机辅助飞机公差优化设计模块,实现了飞机公差的计算机辅助分析和分配功能;建立了实用、可靠的飞机公差数据库,实现了飞机公差的计算机自动查询功能.通过飞机公差分析和公差分配的具体设计实例,验证了研究成果的正确性,初步实现了飞机公差设计的计算机化,为飞机公差设计的数字化提供了技术参考.
In order to solve the problem of aircraft tolerances computerization,the modeling techniques of aircraft tolerance were researched.Using UG（UniGraphics） second development technology and VC＋＋,computer-aided aircraft tolerance optimization design modules were developed in the UG platform to realize computer-aided aircraft tolerance analysis and tolerance distribution.A practical and reliable aircraft tolerance database was created to realize aircraft tolerance automatic inquiry.Finally,the applied examples of aircraft tolerance analysis and tolerance distribution were given.The examples verify the correctness of the research results to complete the preliminary computerization of aircraft tolerance design and provide a technical reference for digital design of aircraft tolerances.
