中文摘要: 从变截面杆作一维纵振动的运动方程出发,建立机械四端网络的数学模型及传输特性方程,导出了圆锥形变幅杆的频率方程和振速比.并在此基础上,用四端网络法设计了工作频率为20kHz的圆锥形超声变幅杆.
Abstract:From the motion equation of the bar which vibrates one-dimensionally and longitudinally, the model of mechanical four-terminal network and the transfer equations are set up, and the natural frequency equation of coniform horn and the ratio of speed of vibration are derived. On this basis, with the help of four-terminal network, the coniform horn working at 20 kHz is designed.
