This paper describes the dynamic analysis method for a spherical resonant actuator using the three-dimensional finite element method (3-D FEM). In this computation, the magnetic field equation is coupled with the electric circuit equation and the motion equation. And the mesh modification method using the Laplace equation is applied for the rotation of the spherical actuator. The dynamic characteristics...
This paper describes the trajectory analysis method for a spherical resonant actuator using the three-dimensional finite element method (3-D FEM). The effects of frequency and phase of the applied voltage on the trajectory of the armature are clarified using this method.
This paper proposes a dynamic analysis method for a novel spiral resonant actuator with two-degree-of-freedom employing the 3-D finite element method (FEM). The effects of the slit structure on the performance of the actuator are quantitatively clarified using this method. Furthermore, the effectiveness of calculated results is verified through the comparison with the measured ones.
