摘要
通过理论分析与模型试验,对水下结构的振动与声辐射进行了研究;讨论了影响声辐射效率的因素以及相应的水下声强测试分析方法;对某水下结构,依据声辐射规律。
An investigation on the sound radiation of the underwater structure was described through the theoretical analysis and tests in water. The influences on the emission efficiency as well as the method of sound intensity survey were discussed. The vibration status of a certain structure was researched on the basis of the sound radiation property by using the reciprocity method.
