The dynamic characteristics of the piezoelectric materials are demonstrated by the ANSYS finite element techniques. Based on the analyses of the modeling results of the monolayer piezoelectric materials, the dynamic characteristics of the multi-layer piezoelectric pile are further investigated. For piezoelectric materials with a certain thickness, it is found that the resulting stroke and output increases with the decrease of the layer thickness which is attributed by the increased layers and substantially unchanged overall-stiffness.

Abstract Supporting forces of magnetic bearings are lower than those of mechanical bearings. In order to solve these problems, this paper proposes a new three-axis active control magnetic bearing (3-axis AMB) with an asymmetric structure where its rotor is attracted only in one axial direction due to a negative pressure of fluid. Our proposed 3-axis AMB can generate a large suspension force in one axial direction due to the asymmetric structure. The performances of our proposed 3-axis AMB are computed through 3-D finite element analysis.
