面向云制造的生产线仿真模型设计

o study the method of resource virtualization in cloud manufacturing(CMfg), an general model design solution on product line is presented. The model include device model and process model. Establish a device model based on D-H model, graph model and ODE model. D-H model is modeling on links and joints, describe the position of links by D-H parameter; graph model is physic model of device, describe the device by vertex and arc, to avoid ambiguity; ODE model establish virtual device in virtual space. process model is based on Petri-net, describe the state and operate of device by conditions and event of petri. Access Petri-net model and plane trajectory for devices, transform control variables to ODE, ODE drive virtual devices to operate and complete virtulization of manufacturing resource.A simulate model based on proposed method is designed and realized, a virtual product expriments about automatic clipping line is given. The expriment results prove the effectiveness of the presented methods.
