Research on Collaborative Design and Virtual Simulation System of Digital Twin for Automated Production Line Based on NX MCD

摘要: 在智能制造与工业4.0背景下，数字孪生技术成为提升自动化生产线设计效率、降低试错成本的关键路径。传统的串行设计模式存在严重的“信息孤岛”现象，各学科团队协作不畅，设计错误往往直至物理样机调试阶段才被发现，导致项目返工成本高昂、开发周期显著延长。为解决上述痛点，本研究基于NX MCD平台，构建了集机械建模、多学科协同、物理仿真与虚拟调试于一体的数字孪生系统；通过运用机电一体化建模、协同管理以及虚实映射与实时通信等关键技术，实现了虚拟碰撞检测、生产节拍分析与控制逻辑验证等功能，显著缩短了项目开发周期，优化了生产流程，并为实现预测性维护奠定了坚实基础，展现出显著的工程应用价值。

Abstract: Under the background of intelligent manufacturing and Industry 4.0, digital twin technology has become a key path to improve the design efficiency of automated production lines and reduce trial-and-error costs. Traditional serial design modes suffer from severe “information silos”, poor collaboration among multidisciplinary teams, and design errors that are often not discovered until the physical prototype debugging stage. This leads to high project rework costs and significantly extended development cycles. To address these pain points, this study constructs a digital twin system integrating mechanical modeling, multidisciplinary collaboration, physical simulation, and virtual commissioning based on the NX MCD platform. By leveraging key technologies such as mechatronic modeling, collaborative management, virtual-real mapping, and real-time communication, the system realizes functions including virtual collision detection, production cycle time analysis, and control logic verification. It significantly shortens the project development cycle, optimizes the production process, and lays a solid foundation for predictive maintenance, demonstrating considerable engineering application value.
