Secondly, the three-dimensional model of rotor group is established by SoildWorks, and the finite element optimization analysis of rotor group is carried out by Simulation. Thirdly, from the results of finite element analysis, the natural frequency and critical speed of the rotor group are obtained, and the corresponding measures to improve the structure of the rotor group are put forward. The analysis of Simulation software shows that the retrofit scheme is feasible and the compressor unit runs smoothly after the revamping.
