摘要
研究机械声源至声辐射传递关系的建模方法。利用Levenberg-Marquardt算法对多种模型组合进行优化计算,建立机械声源至声辐射的传递关系模型。通过仿真研究,验证建模方法的有效性。利用模型对3种典型设备单独运转的声辐射进行估算,估算结果与实测结果吻合,表明建立的模型可用于描述机械声源至声辐射的传递关系。
The modeling method of transmission relationship of mechanical noise sources to radiation was studied.The arithmetic of Levenberg-Marquardt was used to calculate the optimal model from the more kinds of models,and the transmission relationship was established from machine in the interior of underwater vehicle to the field of underwater acoustic.The modeling method is efficiency that validated by simulation.Furthermore,the pre-estimate of the radiated noise for three kinds of machines were conducted by using this model,and results are remarkable consistency with measurements both on the value and the trend.The results indicated that the model can make use of describing the transmission relationship.
