摘　　要：根据职业院校机电一体化实训现状与需求,借鉴数字孪生技术的实践经验,提出了数字孪生机电一体化实训平台的开发思路。基于西门子NX/MCD,以原有的INGO-558光机电一体化实体设备为例,阐述了光机电一体化设备的组成、运动流程;运用SolidWorks 2019绘制三维模型;应用西门子NX/MCD软件配置三维模型机电属性、设置信号;利用博途(TIA)软件建立模型MCD信号和PLC变量连接;编写PLC程序,配置PLC硬件平台、网络通信、工艺流程程序以及设计HMI界面;编译程序后,利用PLCsim Advanced下载程序,启动SIMIT仿真验证PLC程序的正确性以及机械结构设计的合理性。当出现与预期不同的情况时,检查PLC程序运行状况和MCD中信号触发情况及仿真序列运行情况,根据对应错误进行修改;当符合预期时,将程序下载至设备的PLC中,快速完成对设备的调试。According to the current situation and demand of mechatronics integration training in vocational colleges,the development idea of digital twin mechatronics training platform for reference to the practical experience of digital twin technology is put forward.Based on Siemens NX/MCD and taking the existing INGO-558 opto-mechatronics equipment as an example,the composition and movement process of opto mechatronics physical equipment are described.3D models are drawn with SolidWorks 2019;Siemens NX/MCD software is used to configure electromechanical properties of 3D model and set signals;TIA software is used to establish the model MCD signal and PLC variable connection.Then,PLC program is written,PLC hardware platform,network communication,process flow program are configured,and HMI interface is designed.After compiling the program,PLCsim Advanced is used to download the program and starts SIMIT simulation to verify the correctness of the PLC program and the rationality of the mechanical structure design.When deviation from expectation occurs,check the PLC program running status and MCD signal trigger and simulation sequence running status will be checked and modify according to the corresponding error;When the results meets the expectations,the program will be downloaded to the PLC of the equipment,the debugging of the equipment is then completed.
