摘要
以激波消声机理为理论基础,采用试验研究与仿真分析相结合的手段,进行了高炮用炮口消声器的设计与研究;采用多腔室消声碗结构,使火药燃气在消声器中产生激波而损失能量,达到降低炮口压力,实现降低炮口噪声的目的。通过仿真分析、试验验证,结果表明安装消声器(内径为Φ50 mm光孔)后,在436 m处,火炮噪声比光膛口时降低了18.34 dB,对高炮安装炮口消声器的研究具有一定的指导意义。
Based on the theory of shock wave muffling mechanism,the muzzle muffler for antiaircraft gun was designed and studied by means of combination of experimental research and simulation analysis.The muzzle muffler structure of multi-chamber muffler was adopted to make the gunpowder gas produce shock wave and lose energy in the muffler,so as to reduce muzzle pressure and achieve the purpose of reducing muzzle noise through experimental verification and simulation analysis.The results show that the noise of artillery was reduced by 18.34 dB at 436 m after the installation of the muffler(with inner diameter of 50 mm aperture),which has certain guiding significance for the research of installing the muffler of artillery.
