Influence of temperature on the vibration control of the laminated composite sandwich plate with a 3D printed PLA core

Abstract

The current study looks at the effect of temperature on the vibration control properties of a laminated composite sandwich plate. The sandwich plates fabricated using the glass-epoxy composite face sheets and the 3D printed PLA core are used for the study. Three PZT5H piezoelectric patches are used for actuating, sensing, and controlling the laminated composite sandwich plate. The proportional controller with constant control gain is utilized to control of vibrating sandwich plate operating at 10° C, 20° C, and 30° C thermal environments. The proportional controller was designed in the basic LABVIEW programming platform. The physical analog input/output modules and amplifier units are effectively utilized to control the oscillating cantilever sandwich plate. The investigation revealed that the vibration attenuation characteristics of the PZT5H patch-assisted proportional controller increase with the increase in temperature. © 2023 Author(s).
