| 中文摘要: |
| 在负载为纯力抗的状况下,利用纵振型变幅杆等效四端网络,对频率方程和放大系数进行了研究．得到了三类常用变幅杆频率方程和放大系数的表达式；并通过MATLAB编程,分别绘制了三类变幅杆共振频率及放大系数随负载变化的曲线图．这将对超声变幅杆的研究和设计提供一定的理论依据． |
| 英文摘要: |
| Based on equivalent four-terminal networks of the longitudinal ultrasonic transformer,the resonant frequency equation and the amplitude magnification coeffi- cient,with reactive load,are studied.The formulas of three kinds of loaded ultrasonic transformers are presented;then,the graphs of resonance frequency and the amplitude magnification coefficient,following the change of load,are charted by the programs of MATLAB.The results may be helpful to the research and design of ultrasonic transform- ers. |
