The invention belongs to the technical field of vibration reduction and isolation for ships, and particularly relates to a modularized truss type floating raft vibration isolation device and a vibration isolation stability maintaining method, equipment on a truss type floating raft is divided into three layers to be installed, and a power system control box is elastically installed on the upper layer through a first-stage vibration isolator; the middle layer is elastically provided with power equipment with large vibration and large power through a first-stage vibration isolator, the middle layer is divided into a sound insulation cover installation area and a sound insulation cover non-installation area, the power equipment with large noise is installed in the sound insulation cover area, and the other power equipment is installed in the sound insulation cover non-installation area. A liquid tank structure is fixedly mounted on the lower layer and used for increasing the overall weight of the buoyant raft and improving the vibration isolation effect; the two-stage vibration isolators are supported on the bases, the four limiting stoppers are arranged on the bases at the same time, and the eight bases are all located at the connecting corners of the bulkhead and the ship body. According to the vibration isolation device, by arranging the devices in a partitioned mode, arranging the vibration isolators at the two ends in a layered mode and arranging the bases at the corners of the structure, the overall structure is good in stability, and the vibration isolation performance can be effectively improved.

    本发明属于船用减振隔振技术领域,尤其涉及一种模块化桁架式浮筏隔振装置及隔振维稳方法,桁架式浮筏上的设备分为三层安装,上层通过一级隔振器弹性安装动力系统控制箱;中层通过一级隔振器弹性安装振动较大、功率较大的动力设备,同时分为安隔声罩、不安隔声罩两个区域,噪音较大的动力设备安装在隔声罩区域内,其它安装在非隔声罩区域;下层固定安装液舱结构,用于增加浮筏整体重量、提高隔振效果;通过二级隔振器支撑在基座上,同时布置四个限位器安装在基座上,八个基座均位于舱壁与船体连接的角落。本申请通过分区布置设备、两端分层布置隔振器、基座位于结构角落的设置,使得整体结构稳定性好,能够有效的提高隔振性能。
