舰船和水下航行器降噪效果模糊综合评估

A Fuzzy Comprehensive Judgment on Noise Reduction of Ship and Underwater Vehicle

以模糊理论为理论依据 ,运用模糊数学的综合评判工具建立数学模型 ,对水下航行器噪声控制的影响因素与影响效果之间的关系进行分析 ,以VisualC ++和VisualBasic语言进行编程计算 ,对影响降噪的诸因素的综合影响效果有了定性的了解 ,并可对各种舰船的降噪效果进行模糊综合评估。

Based on the fuzzy theory, the mathematical model was been built using comprehensive judgment method of fuzzy mathematics. The analysis of the relation between the influence factors and the influence results was carried out in taking control of noise of underwater vehicle. According to the calculation and judgment of many factors having influence on noise reduction of underwater vehicle by means of the special software written in Visual C++ and Visual Basic, we have found out in generally the relation between the influence factors and the comprehensive influence results of noise reduction. The fuzzy comprehensive judgment method mentioned in this paper may be applied to the noise reduction judgment of some kinds of marine ships.
