中文摘要:
      本文导出了余弦型纵振变幅杆和扭振类余弦型变幅杆的频率方程及参数的计算式和曲线,对简单型杆及由其与圆柱型段和双曲正割型段组成的复合杆件进行了谐振频率和放大系数测试,实验结果与理论值基本吻合。
英文摘要:
      Two new types of ultrasonic transformers longitudinal cosine type and torsional similar-cosine type are studied. The frequency equations and formulae for calculating the performance parameters and the dimensions of the horns are given. The resonant frequency and amplification of some simple horns of the new types and some complex horns composed by the new tapers and cylinder, or hyperbolic secant taper have been measured. The experimental results basically agreed with theoretical values.
