Vibration Control Technology of Thin-wall Structure with Piezoelectric Patches Array

The work aims to form the modeling method of thin-wall structure with piezoelectric patches array and verify the control effects by time domain simulation. The dynamic model of thin-wall structure with piezoelectric patches array was established by finite element and ANSYS APDL parametric language was adopted to compile the program to automatically generate the finite element model of thin-wall structure with piezoelectric array shunt circuit and carry out the dynamic simulation research. The time domain simulation of periodic piezoelectric structure connected with shunt circuit was realized, and the effectiveness of piezoelectric array shunt damping technology in vibration control of thin-wall structure was verified. The modeling and simulation method of thin-wall structure with piezoelectric array elements can provide technical support for vibration control of aviation thin-wall structures.
