摘　　要：对于装备制造业智能化、网络化、数字化变革需求,新一代信息技术应用在研发设计教学中已经是一种趋势。通过研究其系统物理层、虚拟层、仿真软件和技术资源,搭建多种数字孪生样机与数字孪生环境,开发基于数字孪生的智能制造教学试验实训平台。通过数字孪生技术,采用模块化设计及机、电、软等仿真手段方法,同步实现硬在环和软在环的双向控制验证。实现完整的产品设计与优化、产品零部件规划与验证、数字化制造工艺仿真、虚拟调试以及PLC逻辑信号的判断和验证。这种平台有效解决在进行实物生产之前的虚拟化实时验证问题,缩短复杂装备研制周期,降低研制成本,并提升装备的性能和可靠性。通过在教学过程中模拟单元机构、设备产线和工厂多应用场景,避免真实演示教学的时间、设备恢复等问题,有效弥补教学资源不足、实验实训中看不到、进不去、危险性大等缺点。Facing the demand of intelligent,networked and digital transformation in the equipment manufacturing industry,the application of new generation information technology in research and development design teaching has become a trend.By studying the physical layer,virtual layer,simulation software and technical resources of its system,various digital twin prototypes and environments are built,and an intelligent manufacturing teaching and experimental training platform based on digital twins is developed.Through digital twin technology,modular design and simulation methods such as mechanical,electrical and software are adopted to synchronously achieve bidirectional control verification between hard in the loop and soft in the loop.Realize complete product design and optimization,product component planning and verification,digital manufacturing process simulation,virtual debugging,judgment and verification of PLC logic signals.The platform effectively solves the real-time verification of virtualization before physical production,shortens the development cycle of complex equipment,reduces development costs,and improves equipment performance and reliability.By simulating multiple application scenarios such as unit structures,equipment production lines and factories during the teaching process,problems such as real demonstration teaching time and equipment recovery are avoided,effectively compensating for shortcomings such as insufficient teaching resources,inability to see,enter and high danger in experimental and practical training.
