汽车三维图纸自动化设计与发布

Automatic Design and Release of Automobile 3D Drawing

针对汽车图纸设计自动化水平低、变更管理复杂及研发周期长的问题,文章以三维MBD模型为基础,提出基于NX和Teamcenter联合二次开发的图纸自动化设计解决方案。首先,开发了图纸模板自动创建工具;其次,基于特征识别算法完成自动标注;最后,开发Check-mate检查项实现质量检查,并自动跟踪图纸发布状态。以副车架图纸设计为例进行验证,结果表明,该解决方案减少了设计、校验、发布和产品管理的时间,提高了图纸设计发布与产品管理的质量。

Aiming at the problem of low automation level,complicate change process and long development cycle of vehicle drawing design,based on 3D MBD model,a solution of automatic drawing design based on NX and Teamcenter secondary development is proposed.Firstly,the automatic creation tool of drawing templates is developed.Secondly,automatic annotation is completed based on feature recognition algorithm.Finally,the Check-mate check is developed to realize the quality check,and the drawing release status is automatically tracked.Taking sub-frame drawing design as an example,the results show that the solution reduces the time of design,verification,release and product management,and improves the quality of drawing design release and product management.
