英文摘要：

In the design of general scroll vacuum pump,the work principle of the general scroll vacuum pump was analyzed.Using engineering analysis soft Pro/Engineer,the solid modeling of the key parts of scroll compressor were built and the whole assembly was finished.The dynamic simulation for the machine was carried out in the engineering analysis soft Pro/Engineer.Using the function of microscope magnify,in the condition of several ten thousand times,the meshing points still touch accurately,and the process dynamic simulation is running in gear,which proves that the general scroll profiles theory and process of seek and solid modeling are correct.The design proof is presented for the general scroll profiles theory and the methodology of single scroll profiles design theory is broadened.
