数字样机在核工业设备全生命周期的应用研究

Application Research of Digital Mockups in Product Lifecycle of Nuclear Industry Equipments

相较于传统的机械系统开发模式,数字样机技术应用于核工业设备这类对安全性、可靠性要求高的复杂装备的开发具有显著的优势。论文明确了数字样机在产品全生命周期不同阶段的作用;针对核工业设备这类复杂机械系统以统一的关系矩阵建立了多层次、多过程的全数据模型,并以三维视图组织数据保证样机的完备性;提出了两种实现异构系统数字样机数据集成的方法;然后以水泥固化线上一种精密的核工业设备自动开封盖装置为例,实现了数字样机的快速创建,及样机对产品后续生命周期的支持;最后在数字样机的支持下完成了物理样机的试制,试验测试证明物理样机技术指标能够满足设计要求。

Compared with the traditional development model af mechanical system, digital mockup technology is applied to the nuclear industrial equipment, which has a significant advantage in the development of complex equipment with high reliability and safety requirements. The roles of digital mockup in different stages of the nuclear industry equipment life cycle were defined; a unified full-data model of multi-level, multi-process was established by relation matrixes for complex mechanical system such as the nuclear industrial equipment, and 3D views were applied to ensure the completeness of data; 2 ways to the integration afthe heterogeneous digital system were presented; And then the rapid generation methods？and the support for the product life cycle of digital mockup were verified taking the auto-open/close-lid device which was a sort of sophisticated nuclear industry equipment as an example ; lastly the physical prototype is trial-produced supporting by digital mockup and the tests prove that the pe^ormance can meet the design requirements.
