Influences of Cutting Tool Load on Impedance Characteristics of Honeycomb Composite Material Ultrasonic Cutting Acoustic System

Ji Huawei;Yu Wenze;Hu Xiaoping;Yu Baohua;Hangzhou Dianzi University;  
The impedance characteristics of a honeycomb composite material ultrasonic cutting acoustic system varied with the cutting tool load.By combing piezoelectric transducer with horn,a hybrid design equation of the acoustic system was put forward based on four-terminal network,and the relationship between load and the impedance characteristics of acoustic system was obtained.The modal analysis and the harmonic response analysis to the acoustic system were carried on by using of the finite element software and the impedance,resonant frequency and output amplitude of the acoustic system were measured by the impedance analyzer and laser displacement sensor.Simulation and experimental results show that the impedance of the acoustic system is increased,and the resonance frequency decreases with the increase of the tool load,but the output amplitudes among theoretical analysis,simulation and experiment are different,which is due to the amplification of the tool.The study has a guiding significance for the design and applications of honeycomb composite material ultrasonic cutting acoustic system.
