船舶机械设备的噪声分析与有效控制方案研究

  目的  针对传统的液压驱动的舵传动装置，基于缩比舵传动装置试验台，开展电气驱动方式振动特性研究。  方法  首先研究舵传动装置在电气驱动下机构本身振动特性与负载力及转动角速度的关系，然后对液压、电气两种驱动方式下机构的振动特性进行对比分析。  结果  试验表明，传动装置产生的振动强度与舵叶加载力、舵角零点位置角速度呈正相关，电气驱动方式产生的振动加速度峰峰值和均方根值与液压驱动相比均降低了40%，有效降低了传动装置的整体振动，  结论  对舵传动装置电气化具有参考价值。

Noise analysis and control scheme of ship machinery equipment

  Objectives  A comparative study of the rudder transmission vibration characteristics of electric drive and traditional hydraulic drive is carried out on the basis of a telescopic rudder transmission test bed.  Method  First, a study is made of the rotational angular velocity and the relationship between the vibration characteristics and load force of a rudder transmission driven by an electric servo motor. Next, the vibration characteristics of the mechanism under hydraulic drive and electric drive are compared and analyzed.  Results  The results indicate that the vibration intensity has a positive correlation with the rudder blade loading force and angular velocity at the zero balance position. Both the peak-to-peak values and root-mean-square values of the vibration acceleration of the electric drive are reduced by 40% compared with the hydraulic drive, meaning that the electric drive can more effectively reduce the overall vibration of the rudder transmission.  Conclusions  The results provide a reference for the electrification of the rudder transmission.
