摘要

为降低舰船设备传递到基础的振动，提出广义质量弹簧减振器。介绍该减振器的结构组成，采用结构导纳综合法对其动力学特性进行分析。为验证广义质量弹簧减振器的减振效果，以某船用滑油泵为对象，采用Adams及Ansys软件构建系统刚柔动力学混合模型，对安装减振器前后机脚加速度频、时域响应进行仿真分析。结果表明，广义质量弹簧减振器不仅能降低设备机脚特定频率的振动，亦能抑制该处中高频振动。

Abstract

To reduce the vibration transferred from vessel equipment to the base, a kind of generalized mass-spring damper was proposed. The structure was introduced, and the dynamical characteristic was analyzed by the mobility synthesis method. In order to verify the vibration reduction effect of the generalized mass-spring damper, the lubrication oil pump on the vessel was taken as an analytical object, which rigid-flexible coupling model was established, the frequency and time responses of the acceleration with and without the generalized mass-spring damper were calculated. The results showed that the generalized mass-spring damper can not only reduce the vibration of the equipment feet at a specific frequency, but also suppress the middle and high frequency vibration.
