| 中文摘要: |
| 本文从扭转振动波动方程出发，推导出了具有“类圆锥”过渡段的复合阶梯型扭转变幅杆的频率方程和放大倍数的解析表达式．从实验和理论上对该复合变幅杆的谐振频率随细端长度和直径的变化进行了测量和计算．通过对比，首次证明了复合振动系统中“局部”扭转共振现象的存在，并给出了其产生条件． |
| 英文摘要: |
| This paper discusses the phenomenon of part-torsion resonance. Starting with the torsion vibration wave-equation. It deduces the frequency equation and amplification ratio of the complex stepped torsional-mode concentrator with a circular cone-like. Then it probes Into the relations between the harmonic frequency of the complex system as well as the length of the slender rod. Through contrast of the theory with experiment, the generating condition of the part-torsion resonance is obtained. |
