| Abstract: | The critical rotary speed,principal mode,and unbalanced response were analyzed of the rotor of a big-sized turbo-expander using the finite element method,and corresponding calculation program was compiled using MATLAB based on the characteristics of the rotors in turbo-expanders.The calculated samples show that the program had fast calculation speed and high accuracy,and was ideal in the dynamic calculation of the rotor in a turbo-expander. |
