摘　　要：为降低调试周期和成本,提前预知系统级风险,基于数字孪生的虚实一致特性,提出了一种基于数字孪生的力能控制式压力机虚拟调试方法,设计了虚拟调试系统.根据力能控制式压力机的多系统协同调试任务,建立了其多物理领域统一模型,即机械、电气等的多领域数字孪生模型,并构建了虚拟控制系统,包括虚拟控制器和控制器-模型接口.通过应用于压力机虚拟调试的实例,展示了基于此数字孪生模型进行虚拟调试的有效性,构建的虚拟调试系统能够验证机械系统、电气系统和控制程序的设计,并确定和优化运行参数,有效避免了实机调试成本高、风险大、周期长等弊端.In order to reduce the cycle and cost of the commissioning process and predict system-level risks in advance,according to the virtual and real consistency characteristic of the digital twin,a virtual commissioning method for the force-power controlled press machine based on the digital twin was proposed,and the system was designed.According to the multi-system coordinated commissioning task of the force-power controlled press machine,a unified model of its multi-physical fields was established,which is a multi-domain digital twin model,including mechanical system,electrical system and so on.The virtual control system consisting of virtual controller and controller-model interface was provided.A use case was developed to verify the effectiveness of virtual commissioning based on this digital twin model.The result shows that the virtual commissioning method which developed in this research can verify the design of mechanical system,electrical system and control programs,and optimize the operating parameters.The commissioning disadvantages such as high cost,high safety risk and long time cost which are usually caused by actual commissioning can be avoided.
