Dynamic mechanical properties of variable friction damper based on new piezoelectric ceramic tubular actuator

Abstract

Based on ANSYS finite element software and combined with the physical properties of piezoelectric materials, the actuating properties of the new piezoelectric ceramic tubular actuator was simulated. In addition, the maximum displacement, output and response frequency characteristics of the actuator were obtained. The results shown that the actuator was suitable for the development of structural vibration control device. The intelligent damper for adjusting friction in real-time was proposed by using the above-mentioned new actuator. In addition, the dynamic mechanical properties of the intelligent damper were analyzed, the constitutive relationship under the sinusoidal simple harmonic action and the calculation formula of the energy consumed in one cycle were obtained.
