Study on Vibration Control of Carbon Fiber Reinforced Composite Laminates
Based on the state vector method and transfer matrix method, the coupled motion equations of piezoelectric ceramic-carbon fiber reinforced composite laminates are established. Dynamic models based on the state vector method and transfer matrix method can better reflect the inherent characteristics of laminated plates with different ply angles. The state space equations of the piezoelectric system composed of carbon fiber reinforced laminates and piezoelectric elements are solved in MATLAB by the established dynamic model. Comparing the analytical results with the finite element results, the simulation results are in good agreement with the analytical results, which verifies the correctness of the model. Through sliding mode control, the vibration time-domain response of laminated plates under different external excitation signals is analyzed. After the control is applied, the amplitude of the output response of the system decreases by about 50%.
