摘　　要：针对数字孪生在可重构制造系统(RMS)的应用问题,提出面向RMS的数字孪生与制造仿真一体化平台(DTMSIP)架构. DTMSIP架构充分适配RMS动态重构特性,可以在RMS构型设计中实现仿真分析.对面向RMS的数字孪生映射进行建模,通过引入孪生实体(TE),实现RMS车间的多源异构数据集成,并分别建立机床与构型的数字孪生映射.建立数字孪生方法在RMS重构中的应用流程,通过信息物理融合迭代与构型仿真优化迭代,DTMSIP可以服务于RMS的系统重构.为了验证所提出方法的可行性,使用虚幻引擎四(UE4)为一套实际的模块化RMS构建数字孪生平台,并将当前构型以及4种规划构型作为仿真输入.通过分析重构成本、生产周期与系统平衡率3项指标,实现对构型的量化综合分析,实现了重构设计流程加速.Digital twin and manufacturing simulation integrated platform(DTMSIP) architecture for reconfigurable manufacturing system(RMS) was proposed, aiming at the application problem of digital twin on RMS. DTMSIP was highly adapted to RMS’s dynamic reconfiguration and can be used for simulation analysis in RMS configuration design. Digital twin mapping for RMS was modeled. By defining twinning entity(TE), heterogeneous multi-source data integration in RMS shop-floor was realized and digital twin mapping for machine tools and configuration was established. The application procedure of digital twin-based RMS reconfiguration was proposed. DTMSIP served the purpose of assisting RMS reconfiguration through iteration of cyber physical fusion and iteration of configuration simulation. In order to validate the proposed method, Unreal Engine 4(UE4) was adopted to implement DTMSIP software for a modular RMS. Current configuration and four planned configurations were input to DTMSIP software for simulation. Quantitative and comprehensive analysis was performed on the configurations taking into consideration cost of reconfiguration, cycle time and line balance, contributing to accelerate RMS reconfiguration design processes.
