    Abstract: The Legendre polynomial method has been extended to the modeling of MEMS resonator disc partially covered with electrodes. The disc has been divided into two areas: one with electrodes and the other without electrodes. For each area, The Maxwell equations and the piezoelectric constitutive equations of motion are studied and solved to yield a frequ... Show More

    Abstract: Compared with the general damper, the MR fluid damper has the advantages of adjustable damping, large damping force and intelligence. Magneto rheological fluid damper is a unique role in the study of vibration, shock absorption, and tactile feedback. When the semi-active vibration control of the structure is carried out by the MR damper, the more a... Show More
