【摘要】：浮筏隔振是船舶动力系统减振降噪的有效方法。将半主动控制技术与浮筏隔振技术相结合,用于船舶动力系统的隔振是一种值得探索和研究的新方法。本文针对半主动控制浮筏隔振系统的可控浮筏隔振系统开展试验研究,其主要工作内容如下： (1)进行实验室已有的浮筏隔振试验系统的分析,重新设计了模拟振源,搭建可控制浮筏隔振试验系统。 (2)对可控阻尼器开展试验研究,参照车辆减振器的试验方法,研究可控阻尼器得电状态和失电状态的示功特性、速度特性、功耗特性。 (3)讨论并确定隔振效果评价指标；分析单层、双层、浮筏和多层隔振系统的隔振特性；讨论常用的半主动控制方法,并确定面向半主动控制的可控浮筏隔振系统的基本控制原则。 (4)在搭建的可控浮筏隔振试验系统上,分别对不同开关控制状态的可控浮筏隔振试验系统进行了试验,通过振级落差研究其隔振效果。 (5)建立单振源可控浮筏隔振试验系统的三自由度模型,并利用MATLAB进行求解,分析其振动特性；建立了可控浮筏隔振试验系统的ADAMS模型,对其振动特性进行仿真。通过与可控浮筏隔振试验系统的试验结果的对比,分析讨论可控浮筏隔振系统的隔振效果。
[Abstract]:Floating raft vibration isolation is an effective method to reduce vibration and noise of ship power system. The vibration isolation of ship dynamic system is a new method worthy of exploration and research. In this paper, the controlled floating raft isolation system of semi-active control floating raft vibration isolation system is studied experimentally. The main work of this paper is as follows:. 1) by analyzing the existing floating raft vibration isolation test system in laboratory, the simulated vibration source is redesigned and the controllable floating raft vibration isolation test system is set up. (2) the experimental research on controllable damper is carried out. According to the test method of vehicle shock absorber, the power performance, speed characteristic and power dissipation characteristic of the controlled damper are studied. (3) discuss and determine the evaluation index of vibration isolation effect; analyze the vibration isolation characteristics of single-layer, double-layer, floating raft and multi-layer vibration isolation system; discuss the commonly used semi-active control methods, The basic control principle of the controllable floating raft vibration isolation system for semi-active control is determined. 4) the vibration isolation test system of controllable floating raft with different switching control states was tested on the system, and the vibration isolation effect was studied by the drop of vibration level. The model of three degrees of freedom of the vibration isolation test system of single vibration source controllable floating raft is established, and its vibration characteristics are analyzed by using MATLAB. The ADAMS model of the vibration isolation test system of controlled floating raft is established. The vibration characteristics are simulated and compared with the experimental results of the controllable floating raft vibration isolation system, and the vibration isolation effect of the controllable floating raft isolation system is analyzed and discussed.
