Effect of Ultrasonic Vibration on the Surface Adhesive Characteristic of Iced Aluminum Alloy Plate

Icings on moving machinery, such as wind turbines and aircraft wings, degrade their performance safety. Ultrasonic vibration is considered one of the deicing methods. In this research, simulations experiments are carried out to explore effect ultrasonic adhesive characteristic ice aluminum alloy plates. Harmonic response analyses conducted analyze changing distributions shear stresses at interface under different frequencies sizes PZT patches. The results show that there optimum side length thickness patch, size iced plate constant. these conditions, high. Then, torque calculate ice. force decreases excitation vibration. When excited frequency 79 kHz, torsional stress 0.014 MPa, which only 7% with no
