1、摘要UG面向过程驱动的技术是虚拟产品开发的关键技术,在面向过程驱动技术的环境中,用户的数据库,真正实现了CAD/CAE/CAM等各个模块之间的无数据交换的自由切换,完全共享零件和产品模型的数据,为协同工作提供了基础。衣夹模型不是一个规则的几何对称体,有很多曲面,而UG软件不仅具有强大的实体造型,曲面造型,虚拟装配和产生工程图等设计功能,在设计过程中还可以进行有限元分析,机构运动分析,动力学分析,完成产品概念设计,模型建立,性能分析和运动分析,加工刀路得生成等整个产品的生产过程,实现真正意义上的无纸化生产。该造型主要分三个步骤完成
2、,首先是建立衣夹的整体模型,设计它的外型,其次是设计弹簧,这个部分比较简单,但尺寸要把握好,最后是装配。主要就是这三个部分,其中第一步比较复杂点,我是通过边叙述边插图的方法写的,这样简单明了,最后一步,装配稍微有些复杂,毕竟不是规则对称的实体,而是曲面实体,所以我是拉伸一个小型圆柱几何体,当然不影响外观,也不影响它的功能。关键词:UG造型衣夹26AbstractUGprocessorienteddrivetechnologyisthekeytechnologyofvirtualproductdevelopmentprocess,
