摘要: 采用Biot-Stoll海底模型分别预测了声波在粗沙、沙质泥和粘土质泥3种典型海底的声衰减系数与声透射系数,通过研究多种海底的声传播特性,建立了掩埋条件下水雷在不同海底和不同掩埋深度的声衰减模型,分析了掩埋对水雷声引信性能的影响。研究结果表明:不同的海底底质、不同的掩埋深度和不同的引信工作频段都会在不同程度下影响水雷声引信的工作性能,在相同的掩埋深度下,10 Hz~5 kHz引信频带内,粗沙海底对声引信的影响最大,粘土质泥对声引信的影响最小,随着海底底质平均颗粒直径的减小和孔隙度的增加,掩埋对声引信的影响有逐渐减小的趋势。

Abstract: Biot-Stoll model is used to predict the attenuation and transmission coefficients of sound in coarse sand, sandy clay and clay mud. A sound attenuation model for buried mines in different sediments and depths is established by studying the acoustic propagation characteristics of various sediments, and the effect of burial on buried mine is analyzed. The result shows that the different sediments,the buried depth and the operating frequency of fuze have different impacts on the functions of mine fuze. In the same depth and the frequency range of 10 Hz~5 kHz, the coarse sand has the greatest influence on the acoustic fuze, and the clay mud has the least influence on the acoustic fuze. The effect of burial on acoustic fuze is decreased with the increase in porosity and the decrease in average particle diameter.
