摘要：在基座腹板与甲板面之间增加阻振质量是有效抑制船舶辅机振动向船体结构传递的手段。本研究以辅机泵的振动传递为研究目的，以阻振质量为研究对象，采用有限元法系统分析阻振质量的几何特性、材料特性以及结构形式等参数对船用辅机振动传递的影响。仿真结果表明，增大阻振质量尺寸、采用合理的构型均能显著降低振动传递。同时考虑轻量化设计需求，提出一种新型口字型阻振质量结构。

Abstract:Adding a blocking mass between the base web and the deck surface is an effective means to curb the transmission of ship auxiliary machinery vibration to the hull structure. This study aims to investigate the vibration transmission of auxiliary pumps， focusing on the blocking mass as the research object. The finite element method was employed to systematically analyze the influence of parameters such as the geometric characteristics， material properties， and structural configuration of the blocking mass on the vibration transmission of marine auxiliary machinery. Simulation results demonstrated that increasing the size of the blocking mass and adopting a rational configuration can both significantly reduce vibration transmission. Considering the requirement for lightweight design， a novel squareframe-shaped blocking mass structure is proposed.
