“…At the same time, it should not be too small, as it would result in boundary reflection waves and reduce the signal-to-noise ratio. Therefore, the size of the model is determined through preliminary theoretical analysis to be 0.6 times the value given in Equation ( 2) (Ye, 2012).…”

Numerical simulation method of finite element is used to study the Rayleigh wave response of underground leakage channel under different Rayleigh wave speeds. By calculating a series of finite element models with different depths of seepage channels and different offset distances and channel spacing, the influence of changes in channel spacing and offset distance on the characteristic signals of the Rayleigh wave response is obtained in the actual detection process. It is summarized that the optimal choice of channel spacing in the detection process is 1m, and the offset distance is 7m when the leakage location is 10m or less, and the relationship equation between the leakage channel location and the optimal offset distance is fitted out when the leakage channel location is more than 10m, which provides the program improvement for the detection of underground leakage channels, and is verified in the engineering examples, which provides the theoretical basis and reference for the reasonable choice of the offset distance and the spacing of the channel in the engineering investigation.

“…In seismic refraction exploration, it refers to the distance between two detectors or receivers. Generally, in Rayleigh wave surveys, the signals received by the two detectors should have sufficient phase difference (Ye , 2012). The selection of inter-station spacing can be adjusted according to the specific field conditions.…”

“…Ge [7] and Dong [8] analyzed the vibration response of the shaft system under various excitations, revealing that the vibration characteristics of the propulsion system are significantly influenced by the modal frequencies of the stern structure. Ye [9] and Jiang [10] experimentally investigated the modal and vibration control methods of the stern structure, and they found that isolator, blocking mass, and constrained damping have significant effects on reducing vibration in different frequency bands.…”

The stern structure of the ship, as the primary source of vibration and noise, has always been widely studied. Conducting an analysis of the vibration characteristics of the stern and determining the impact of local structures on the complex coupled vibration in the stern section are particularly important aspects of research. This paper employs the structural-acoustic coupling methodology to investigate the vibration features of the stern of a ship. The study explores the influence of variations in parameters such as the rudder, stern frame, and shaft system on the vibration response of the stern. The results provide valuable insights into controlling vibration and noise in the stern section of ships, as well as informing the design of related structures.
