基于NX/Open和MFC的弹簧设计系统开发

摘要

针对多种弹簧设计的计算流程,提出一种可行的基于NX7.5软件和Windows平台进行弹簧设计二次开发的方案,将弹簧设计的所有设计计算流程合并为一体.在.NET环境下,通过VS 2005软件中的微软基础类(Microsoft Foundation Classes,MFC)和NX/Open API程序来完成弹簧设计的NX二次开发流程,介绍了其中的关键技术.最后对开发的三维建模程序进行测试.测试结果表明:程序正确无误,大大提高了弹簧类通用件在NX平台上的设计效率.%For a variety of design and calculation of the spring design process,a viable program of the secondary development based on the NX and Windows platform is shown,and design calculations of the spring design process are merged into one.By MFC and NX/Open API,the secondary development of spring design is completed in.NET environment,and the key technology is shown.Finally,the three-dimensional modeling program is tested,and the design efficiency is improved highly in the NX platform.
