Vibration of a Sliding Vane Impacting on the Stator in a Rotary Compressor 2008-01-2720

This study analyzes vibration of a sliding vane impacting on a stator in a rotary compressor. The impact of the vane on the stator is analyzed by simulating a shell impact. Two-dimension plane strain approach is used to derive governing equations and the finite element method is used to determine natural frequencies and vibratory modes of a vane. The calculated results are compared and show good agreement with those obtained by using ABAQUS software. The vibratory amplitude of the vane in the first mode is larger than other modes. Therefore, the first vibratory mode shape with the natural frequency of 976 Hz and the maximum vibratory amplitude of 0.012 mm is the most important mode for consideration.
