Modal Analysis for the Vibration Isolator of the Laminated Curved Plate

Based on the APDL parametric design language, the models of the first to the tenth-order for the vibration isolator of the laminated curved plate were analyzed. The natural frequencies and maximum deformation for resonance of all modes were obtained .Then the curves of the influences on the natural frequency which was influenced by the thickness of the curved plate were concluded. The result shows that the thicker curves plate is, the smaller the value of the natural frequency is.
