摘要:
该文对某小口径步枪的超声速弹和亚声速弹进行膛口噪声抑制作用实验研究,分析了2种枪弹根据测点距离枪口的不同位置得到的降噪量,将安装了单腔和多腔消声器的装置与无膛口装置的测量数据进行对比,得到降噪量随距离变化的规律;针对枪弹单发和连发情况进行频谱分析,得到相应的幅频特性曲线;最后分析了消声性能的影响因素。
Abstract:
An experimental study about muzzle noise suppression is conducted on supersonic and subsonic bullet of a minor-caliber rifle.The noise reduction measured at measuring points which have different distances from muzzles is analyzed for the two bullets.The data measured on the rifles with single-chamber and multi-chamber are compared with the data measured on the rifle without muzzle device.The effect of distances on noise reduction is obtained.The frequency spectrum analyzer is conducted for the single and automatic fire of a rifle.The corresponding amplitude-frequency characteristics curves are acquired.The influencing factors on noise reduction are analyzed.
