Abstract: Aiming at the direct influence of the vibration of this grip arm type anti stack mechanism to the structural stability and the quality of cone yarn as product, the vibration performance of the grip arm type anti stack mechanism was carried out, the 3D geometry entity model was established in Pro/E and modal analysis was generated by using the function of finite element analysis in ANSYS Workbench. And the natural frequency, inherent vibration mode and the deformation were gotten. The working frequency and the natural frequency were compared and analyzed about the grip arm type anti stack mechanism. Considering that there were chances to generate resonance in abnormal working state, the inherent vibration mode and the deformation were analyzed and the weak link in working of grip arm type anti stack mechanism was found. And the advice of improving was raised correspondingly. The results indicate that the working frequency is less than the minimum natural frequency, there is no chance to generate resonance in normal working state. The cylinder ingot is the most weak link while resonance happened occasionally.
Key words: anti stack mechanism; modal analysis; natural frequency; inherent vibration mode
