为了避免振动对船舶安全稳定运行的消极影响，研究船舶主机设备振动智能控制方法。采用节点导入有限元建模方法构建主机设备有限元模型，获取主机设备运行情况以及振动详细数据，引入由互相对称的2组偏心质量块式电力作动机构形成的电力作动器，采用伺服三环控制对主机设备振动控制作动器进行环路设计，通过电机主动轮启动偏心质量块，同时调整偏心质量块的位置，实现消振力控制输出，完成主机设备振动智能控制。实验证明，该方法可以实现船舶主机设备模型的建立，可视化展现主机设备电磁性能、振动和热特性等，并有效控制船舶主机设备的振动幅度，其中控制后的船舶发电机的振动等级达到优等级。
Research on intelligent vibration control methods for ship main equipment to avoid the negative impact of vibration on the safe and stable operation of ships. Using the node import finite element modeling method to construct a finite element model of the ship′s main equipment, obtain detailed data on the operation and vibration of the ship′s main equipment, and introduce an electric actuator formed by two sets of symmetrical eccentric mass block electric actuators. A servo three loop control is used to design the vibration control actuator of the ship′s main equipment, and the eccentric mass block is activated by the motor driving wheel, Simultaneously adjust the position of the eccentric mass block to achieve vibration reduction force control output and achieve intelligent vibration control of the ship′s main equipment. Experiments have shown that this method can establish a model of ship main equipment, visually display the electromagnetic performance, vibration, and thermal characteristics of the main equipment, and effectively control the vibration amplitude of the ship main equipment. The vibration level of the controlled ship generator reaches the optimal level.
