火炮产品结构管理模块开发的关键技术研究

Research on key technology in development of product structure management oriented gun

产品结构管理作为基于PDM技术的火炮虚拟样机设计数字化平台的核心模块,对于平台框架有着重要影响。针对火炮具有零/部件数量巨大、产品结构层次多、装配关系复杂,以及零/部件重用率高等特点,对其产品结构进行,分析并设计了火炮产品结构管理模型及其数据库;提出了适用于火炮产品结构树生成的策略;并对借用件在数字化平台中的管理等关键技术予以研究。从用户测试的反馈来看,该模块可有效地支持对火炮虚拟样机的数据化管理。

As a core module of the digital platform supporting gun virtual prototype design, Product Structure Management （PSM） plays a vital part to the platform framework. According to the characteristic that the large number of gun parts, the multi-tier archi-tectures, the complex assembly relationship and the high parts reuse rate of gun virtual prototype PSM, the product structure is an- alyzed. The gun PSM model and its database is designed. The strategy of tree construction suitable for gun is put forward. The key technology of communal part management in digital platform is researched. Judging from the feedback of user testing, the PSM module could efficiently support the management of gun virtual product data.
