英文摘要：

By the current simulation technology research of pumping, an application of CAD/CAM technology com- bined with virtual prototyping simulation approach was proposed. The working principle of the new pumping unit is described firstly ,Then Adams is used to establish comn~utation reducer virtual prototype model, Assuming a certain pumping conditions, and carry on simulation analysis to the organization, get the speed curve and force curve of the key parts, and the commutation principle of the commutation reducer is analyzed through these curves. Analysis of the force curve can pro- vide the basis for the finite element analysis of the pumping unit. And provide guidance for its dynamic optimization and fa- tigue life prediction.
