为了缩短尾翼稳定脱壳穿甲弹的开发周期，提出一种采用UG三维实体建模软件的虚拟装配技术。以UG三维建模软件为基础，选择自底向上的设计模式，通过分析尾翼稳定脱壳穿甲弹零部件的结构特点，分别以弹托和尾翼为例说明了对旋成体及非旋成体零部件的建模方法，对已建好的零部件通过它们之间的约束关系对弹丸进行了装配，同时实现了对弹丸爆炸图的创建；采用 UG 自带的分析功能对装配模型进行了干涉分析，分析结果表明：设计模型合理，并根据弹丸的装配顺序实现了在虚拟装配环境中对装配顺序的仿真及仿真视频文件的制作，采用此技术可以在尾翼稳定脱壳穿甲弹的设计和研发过程中起到很好的帮助作用，从而提高了产品设计质量，缩短了产品开发周期。

In order to shorten the development period for armor piercing fin stabilized discarding sabot (APFSDS), a virtual assembly technology of using UG 3D solid modeling software virtual assembly technology is proposed. By calculated the structural characteristics of APFSDS parts, respectively to sabot and empennage for example explains the modeling method for body of revolution and non rotary body parts, the completed parts are assembled for projectile by constraint relation between them, and creator this projectile explosive drawing; using the analysis function of UG conducted interference analysis for assembly model, the analysis results indicate that the designed model is reasonable, and according to the assembly sequence of the projectile realizes simulation of the assembly sequence and production simulation video files in virtual assembly environment. The results showed that using this technology can play a very good help in the APFSD design and product development process, thereby improves product design quality and shortens product development cycle.
