隔振装置是降低舰船机械噪声最重要的技术之一, 目前已有大量文献对舰船隔振装置技术进行了
研究, 但系统, 全面地论述其技术特点, 应用和进展, 尤其是我国在该领域进展的文献相当缺乏 …

This study investigates the influence of blade number on the propulsion performance and
excitation force of pump-jet propellers (PJPs) using computational fluid dynamics. The …

The propeller fluctuating force is being recognized as the dominant source of underwater
radiated noise, its accurate acquisition is thus necessitated for a reliable acoustic-structure …

Abstract Autonomous Underwater Vehicle (AUV) parameterization is a geometric
modification method, and can quickly obtain excellent structure with low vibration and noise …

A dynamic vibration absorber (DVA) with negative stiffness is proposed to suppress the
longitudinal vibration transmission along a marine shafting system. Stiffness models of the …

This paper investigates the structural and acoustic responses of a coupled propeller-shafting
and submarine pressure hull system under different propeller force excitations. The entire …

Inner substructures, which can be generally compartmentalized into axisymmetric and non-
axisymmetric ones, are believed to significantly affect the vibro-acoustic characteristics of …

This paper presents a dynamic vibration absorber with negative stiffness (DVANS) in
controlling the first longitudinal mode of the propulsion shafting system. The dynamic …

Experimentally investigating the vibration characteristics of a pump-jet propulsor in water is
challenging. In this study, the characteristics of flow-induced vibration and acoustic radiation …

Pump-jet propulsors are inevitably affected by shafting vibrations in actual operating
conditions, especially the longitudinal bearing force, which is the main inducing factor of hull …
