中文摘要 | 參考國內外相關文獻,我們提出設計槍口抑制裝置之結構,並以氣動力學、聲學學理及工程經驗,考量足以影響抑制效率的控制因子計有:(1)抑制裝置前蓋之有無;(2)裝置外筒側孔之有無及大小;(3)延伸管側孔之有無及位置;(4)設置外筒內徑之大小;(5)設置外管長度。本文針對槍口噪音品質特性,以田口方法之隱健性設計為基礎,佐以傳統實驗設計方法與變異數分析,求得影響抑制效率的顯著因子及控制因子水準最佳組合,並確保穩健性設計的再現性。本文經實驗與分析,得到影響槍口噪音抑制效率之顯著因子,為裝置側孔直徑及延伸管側孔位置兩因子。經重複驗證實驗確認,所求得的最佳因子水準組合比未加裝任何槍口裝置時有25.69(dB)的改善效果。 |
英文摘要 | Based on the existing research, theory of acoustics and engineering experience, the critical design factors which influence its performance are found to be: (1) existence of the font cover (with or without), (2) diameter of the outside exhaust hole (or with no hole at all), (3) location of the exhaust hole on the extension tube (or with no hole at all), (4) diameter of the outer tube, (5) length of the outer tube. Taguchi robust design method and the analysis of variance (ANOVA) are used to obtain the optimal design for the rifle muzzle noise reducer. The result shows that main factors for reducing the muzzle noise are “the diameter of the outside exhaust hole” and “the location of the exhaust along the extension tube.” On the other hand the critical factor for reducing the muzzle flash is the existence of the front cover of the muzzle device the muzzle noise can be reduced up to 25.69 dB. |
