Solidworks自动武器消声器设计

摘要消声器是一种利用声学原理降低噪声的装置，在工业、航空、航天、交通、军品以及人类的生活环境得到了广泛的运用。本文就某冲锋枪消声器结构分析与设计过程进行论述，对冲锋枪膛口噪声的特性进行分析，根据膛口噪声的成因和规律，并借鉴国外武器消声器装置的设计思想进行设计，确定整个装置的形状特征和结构参数；利用CAD、Solidworks软件对消声器的结构进行设计，分析了其消声器效率，并将所得到的的结果与冲锋枪的原始噪声数据进行对比得出结论。60663

计算结果表明，该消声器装置对冲锋枪膛口噪声有较好的抑制作用，基本上满足了设计指标，但有待实验的进一步验证。

Title The Design of the Silencer of Automatic weapons

Abstract

Muffler is a noise reduction device using acoustics,whith has wide applications.in the industry,aviation,aerospace，transportation， military and human life environment.

In this paper，the structural analysis and design process of a submachine gun silencer are discussed,and this muzzle noise characteristics were analyzed，According to the producing reasons and laws of the muzzle noise, and referring to the muffler design ideas of foreign small arns,the sharpe and structural parameters of the entire device were determined.By CAD and Solidworks ,the structure of the silencer was designed,and the noise reduction was also analysed,The results were obtained by comparing the data the original noise conclusion.

The results show that desihned the muffler of the submachine gun has better noise reduction effect.And basically meets the design specifications，but needs to be confirmed by further experiments.

Keywords Muffler SPL Sound power level Silencer Bowl muzzle pressure
