The bending effect of piezoelectric quartz is investigated by the theories of elasticity and electromagnetism. First the bending stress is deduced using mechanics of material. According to piezoelectric equation the volume and surface bound charge densities by bending are calculated. Using Finite Element Method, the distribution of the electric field in quartz bar is simulated. Based on the theoretical...
In this paper, a mechanism based on flexible hinges and semi-cylindrical revolute joints to amplify the displacement of stack-type piezoelectric ceramic actuator is designed, and dynamic characteristics of the structure are discussed. The mechanism incorporates two semi-cylindrical revolute joints and some flexible hinges. The models of stress and friction moment of semi-cylindrical revolute joint...
The bending effect of a piezoelectric quartz beam under uniformly distributed load is studied. First according to the anisotropic elasticity, the differential equation in the form of plane stress function is obtained, and then the bending stress components are calculated. By the piezoelectric equation the polarization is obtained. By means of the electrostatic theory in the presence of matter the...
