摘　　要：在旋转超声波加工过程中负载的变化会引起振幅衰减,进而造成加工精度和加工效率降低。本文针对非接触供电旋转超声加工系统在加工过程中振幅衰减的问题,首先,通过静态加载实验,获得了负载对超声振子电学参数的影响规律;其后,在此基础上进行了超声振子的非接触能量传输系统的加载实验,得到负载对能量传输特性的影响规律。实验结果表明,超声振子的电学参数受负载力大小、负载力方向和被加工材料特性的共同影响而发生改变,超声振子电参数改变引起了非接触供电超声系统输出功率的改变,进而导致了振幅衰减的问题;本文采用了串联谐振下主边串联电容、副边并联电容的电路补偿方式来减小振幅的衰减。本文的研究成果为解决振幅衰减问题提供了实验依据。In the process of rotary ultrasonic machining,the change of load will cause amplitude attenuation,which will lead to the decrease of machining accuracy and efficiency.In this paper,in order to solve the problem of amplitude attenuation in the machining process of the rotary ultrasonic machining system with non-contact power supply,the influence of load on the electrical parameters of ultrasonic oscillator is obtained through static loading experiment.On the basis of the static loading experiment,the loading experiment of the non-contact energy transmission system of ultrasonic oscillator is carried out,and the effect of load on energy transmission characteristics is obtained.The results show that the electrical parameters of the ultrasonic oscillator are changed by the combined influence of the load force,the direction of the load force and the characteristics of the machined materials.Change of the electrical parameters of the ultrasonic oscillator leads to the change of the output power of the ultrasonic system with non-contact power supply,which leads to the problem of amplitude attenuation.In this paper,the circuit compensation method of main side series capacitor and secondary side parallel capacitor is adopted to reduce the amplitude attenuation.The research results of this paper provide an experimental basis for solving the problem of amplitude attenuation.
