The stiffened structure has a complex effect on signal propagation and poses difficulties in leakage location technology. In order to solve this problem, this paper proposes a frequency energy ratio mapping method (FERMM). The method divides the grid on the structure in advance, compares the signal of the distributed sensor with the reference signal to generate a mapping matrix frome the energy ratio vector. When a leak at an unknown location occurs, the energy ratio vector is formed by the same method and matched with the mapping matrix to locate the unknown leakage. The energy ratio vector of this method are only related to the propagation path and are independent of the spectral characteristics of the leakage and the frequency response characteristics of the receiving sensor. FERMM has the adaptability to complex structures and can locate continuous signals for a fast real-time process. The FERMM was verified by 120 sets of experiments. The results show that the average posit...

基于频率能量比映射法的加劲结构连续渗漏位置研究

加强结构对信号传播具有复杂的影响，并且在泄漏定位技术中造成困难。为了解决这个问题，本文提出了一种频率能量比映射方法（FERMM）。该方法预先在结构上划分网格，将分布式传感器的信号与参考信号进行比较，以根据能量比矢量生成映射矩阵。当在未知位置发生泄漏时，通过相同的方法形成能量比矢量，并与映射矩阵匹配以定位未知泄漏。该方法的能量比向量仅与传播路径有关，并且与泄漏的频谱特性和接收传感器的频率响应特性无关。FERMM具有对复杂结构的适应性，可以定位连续信号以进行快速实时处理。通过120组实验验证了FERMM。结果表明，平均假设...
