| 摘 要： | 本文建立了火箭强声发生器类比电路模型。仿真分析了二次谐波与螺旋式入口谐振腔在强声发生器中作用。结果表明二次谐波与不同谐振腔入口对谐振腔归一化阻抗和强声发生器频率响应曲线有重要影响。二次谐波可使谐振腔归一化阻抗发生变化,导致强声发生器频率响应曲线失真。螺旋式入口谐振腔可抑制强声发生器二次谐波失真,并对发生器频带扩展均有一定的作用。

| Abstract: | The analogy circuit models of the rocket strong noise device have been established in this paper. The effects of the second-order harmonic and the spiral entrances resonance cavity have been simulated and analyzed. Results show that the second-order harmonic and the spiral entrances resonance cavity play an important role to the Normalized Impedance of resonance cavity and frequency response of the strong noise device. The second-order harmonic can change the Normalized Impedance of the resonance cavity, and cause the distortion of Frequency Response; the spiral entrances resonance cavity can restrain the distortion, and extend the range of the Frequency Response. |

| Keywords: | strong noise device spiral entrances resonance cavity second-order harmonic normalized impedance frequency response |
