Vibration control of cylindrical shells with a hybrid photovoltaic/piezoelectric actuation mechanism

Abstract

Photovoltaic materials, which can directly turn light energy into electric energy, can offer the advantage of generating large voltages without external power supplies. When a near ultraviolet light illuminates on polarized PbLaZrTi (PLZT) materials, an electrical field can be generated along the spontaneous polarization direction due to the phovoltaic effect. This voltage generation mechanism exhibits many advantages, such as (1) high electrical output voltage, (2) wireless energy generation, (3) immune from electric/magnetic disturbances, (4) remote or non-contact control. In this study, Distributed vibration control of cylindrical shells using a hybrid photovoltaic/piezoelectric actuation mechanism is investigated. The light-driven photovoltaic generator induced voltage is used to drive a skew-quad piezoelectric actuator which can induce non-uniform control froces and control moments. Based on theoretical analysis and experimental validation, the constitutive equations defining the piezoelectric actuator induced actuation strain under the actuation mechanism are presented. Each region of the actuator system can induce both positive and negative control forces and moments using logical switches to shift the sign of control voltage of actuator system. Control effectiveness with constant light intensity control algorithm is evaluated and the time history analysis is presented.

The experimental analysis on the driving characteristics of photo response torsion actuator

“…He et al (2016) and Chen and Zheng, 2019) studied the multimodal vibration control of photo-electric laminated thin cylindrical shells through self-organizing fuzzy sliding mode control, and then, the size-dependent models of 0-1/0-3 polarized PLZT unimorphs and bimorphs based on a modified couple stress theory were investigated. Jiang et al (2014) conducted the vibration control of cylindrical shells using a hybrid photovoltaic/piezoelectric actuator. A lot of research has been done on the closedloop control system by Wang et al (2017aWang et al ( , 2017b, and it has been applied to the control for deflection of cantilever beam with hybrid photovoltaic/piezoelectric actuation mechanism.…”

Study on semi-active particle damping technology for offshore platform truss structure

“…The offshore platform truss structure will be inevitably affected by wind, waves, ocean currents, and ice seismic [1], and under this harsh environment for long term [2], this may create noticeable vibration to the offshore platform truss structure which can increased the fatigue damage, deduced the reliability of the system, affected the structure safeness and durability. The vibration control technology of offshore platform has got more and more attention [3,4], at present viscoelastic damping technology is often to be used, which has good vibration reduction effect [5], but due to the devices long term exposed to long term high-energy ultraviolet light and salt spray radiation [6,7], viscoelastic damping materials are easy to aging, failure and reduce its operational life time [8].…”
