【Abstract】 Based on virtual prototype technology (VPT), the simulation model of 3-UPS parallel machine tool is modeled and the simulation scheme is planed. The pivotal parts that have influence on the total machine tool are confirmed by dynamic simulation. The elastic bodies of the pivotal parts are established in MSC Adams. Dynamic response, natural frequencies and other dynamic parameter of the elastic parallel mechanism are found out by dynamic simulation analysis which are the base condition of the optimization design of parallel machine.更多还原
