The screw rotor was a main part of the single screw compressor. The crack of the screw rotor would lead to fault of the single screw compressor. Therefore it was necessary to have fault diagnosis for the screw rotor. The wavelet finite element method was used to analyze the fault of the screw rotor. The changes of the natural frequency reflected the location and sizes of the cracks. The effect of main sizes including the length, the width and the depth on the natural frequency was studied, which offered the theoretical guidance for the fault diagnosis of the screw rotor in the further researches.
