摘要
推力轴承基座是螺旋桨纵向激励向船体传递的主要路径。针对推进轴系纵振控制问题,建立简化的螺旋桨-轴系-推力轴承基座耦合振动模型,并采用四端参数法求解模型干扰通道与控制通道的频响函数。采用滤波自适应算法进行控制仿真,结果表明,在推力轴承基座上施加纵向控制力,控制策略能使推力轴承纵向振动得到有效控制。将作动器对称安装于推力轴承基座,通过作动器输出力抵消干扰激励的影响,进行控制原理验证。试验结果表明,自适应控制方法能有效抑制推力轴承基座的纵向振动,功率谱幅值下降90%左右。
The thrust bearing in a propulsion shafting is the main path for longitudinal vibration to transmit from the propeller to the hull. A simplified propeller-shaft-thrust bearing vibration model is established to study the active longitudinal vibration control. The four-pole parameters method is adopted to derive the frequency response functions of the disturbance and control channels,and the filtered-LMS based adaptive algorithm is used in control simulation. Numerical simulation has shown that the adaptive control strategy can reduce longitudinal vibration of the thrust bearing effectively when the longitudinal control force is exerted on the thrust bearing. To verify the control strategy,two longitudinal actuators are mounted on the thrust bearing housing symmetrically,and response to the controller to cancel the effects of the disturbance. Experimental results demonstrate that the adaptive control method can suppress the longitudinal vibration of the thrust bearing effectively,and the power spectra decrease by about 90%.
