Semi-Active Vibration Suppression of Rotor Shafting Based on MRE Actuator
针对直升机尾传动轴系振动抑制的需求,提出了一种基于磁流变弹性体(Magnetorheological Elastomer,MRE)作动器的转子轴系振动半主动抑制方法.为分析MRE作动器控制电压对转子轴系动力学特性的影响,建立了该轴系动力学模型,并采用开关控制算法,实现了转子轴系振动的半主动抑制.最后,搭建实验台,完成了基于MRE作动器的转子轴系振动半主动抑制的实验验证.实验结果表明,MRE作动器能够实现转子轴系振动的半主动抑制,可以有效降低转子轴系的过临界振动,轴承附近两个测点的振动抑制效果分别为17.57%和18.22%.
Aiming at the requirement of vibration suppression of helicopter tail drive shafting,a semi-active vibration suppression method of rotor shafting based on the magnetorheological elastomer actuator is proposed.In order to ana-lyze the ability of vibration reduction,a dynamic model of rotor shafting is established,and the influence of MRE actua-tor control voltage on the dynamic characteristics of rotor shafting is analyzed.The active switch control algorithm is used to realize the semi-active suppression of rotor shafting vibration.Finally,the experimental bench is built to com-plete the experimental verification of the semi-active vibration suppression of the rotor shafting based on the MRE ac-tuator.The experimental results show that the MRE actuator can realize the semi-active vibration suppression of the ro-tor shaft-train which can effectively reduce the over-critical vibration of the rotor shafting,vibration suppression levels at two bearing-adjacent measurement points reached 17.57%and 18.22%,respectively.
