摘要

摘要: 介绍了能降低船舶推进轴系纵向振动的推力轴承主动减振液压控制装置，建立了推力轴承纵向振动及主动减振液压控制装置液压系统数学模型，利用MATLAB软件，对推进轴系所受螺旋桨的激励力、纵向振动位移及加速度进行了仿真分析。结果表明：主动减振液压控制装置能有效解决推进轴系的动态刚度与支承刚度之间的矛盾；且具有推进轴系纵向位移范围小、加速度响应幅值低以及减振降噪效果明显等特点，可为船舶推进轴系的研制提供技术支撑。

Abstract: The active vibration control device of thrust bearing which can reduce the longitudinal vibration of the propeller shaft is introduced in this paper. The mathematical models of hydraulic system for the longitudinal vibration of thrust bearing and active vibration reduction hydraulic control device are established; Based on the MATLAB software, the exciting force by the propeller, the longitudinal vibration displacement and acceleration of the propulsion shafting are analyzed in the simulation. The results show that the active damping hydraulic control device can effectively solve the contradiction between the dynamic stiffness and the bearing stiffness of the propulsion shaft system. And it has the characteristics of low longitudinal displacement range, low acceleration response amplitude and obvious effect of vibration reduction, It can provide technical support for vibration reduction of ship propulsion shafting.
