摘　　要：针对当前普通四工位刀架无法进行刀具状态监测的问题,运用数字孪生技术进行了新型四工位刀架的设计开发。综合运用西门子NX、TIA、PLCSIM Advanced、SIMATIC NET等软件开展了新型四工位刀架机械结构设计、电气控制系统设计及MCD-TIA机电联合仿真。以新型四工位刀架换刀动作过程为例,验证了基于MCD-TIA仿真的数字孪生设计方案的可行性。进行了新型刀架样机系统的搭建与测试,结果表明:新型刀架换刀速度优于900 ms/工位,振动及温度数据采集响应时间低于50 ms。数字孪生的设计方法实现了机电产品研制过程中机械、电气、控制等多学科的并行设计,提升了各学科间信息融合的效率,有利于产品性能的迭代优化。In view of the problem that the common four-position tool holder cannot monitor the tool condition,a new four-position tool holder is designed and developed by using digital twin technology.The mechanical structure design,electrical control system design and MCD-TIA electromechanical simulation of the new four-position tool holder are carried out by using Siemens NX,TIA,PLCSIM Advanced and SIMATIC NET software.The feasibility of the digital twin design method based on MCD-TIA simulation is verified by taking the tool change process of the new four-position tool holder as an example.The prototype system of the new tool holder is built and tested.The results show that the tool change speed of the new tool holder is better than 900 ms/position,and the response time of vibration and temperature data acquisition is less than 50 ms.The digital twin design method realizes the concurrent design of mechanical,electrical,control and other disciplines in the process of mechanical and electrical product development,improves the efficiency of information fusion among disciplines,which is conducive to the iterative optimization of product performance.
