We illustrate the importance of noise reduction of underwater weapon launch tube, and summarize the classification of underwater launch tube and the main sources of launching noise.───阐明了潜用武器发射装置发射噪声控制研究的重要意义,归纳了潜用武器发射装置的分类以及武器发射噪声的主要来源。
Based on the sound absorption mechanism of Helmholtz Resonator, the advantage of soft tube length is fully used in the new structure, and thus the low-frequency noise can be controled easily.───了一种新型的宽频带共振吸声结构,该结构基于赫姆霍兹共振吸声机理,并充分利用了软管在长度上的优势,易于实现对低频噪声的控制。
Aimed at the jet noise which is induced by the expand structure and tail tube in the resistant muffler, a finite element model at low Mach number was developed.───针对抗性消声器中扩张结构和尾管引起的射流噪声问题,建立了低马赫数射流噪声有限元分析模型。
