中文摘要：
A new type of shear viscous damper for rotating machinery is designed.The new damper with good stability and reliability can inhibit all kinds of frequency multiplication vibration caused by misalignment in the condition of non-stop machine.It analyzes and discusses the use of the shear viscous damper for misalignment vibration response inhibition with a finite element method,and experiments are extensively carried out with a laboratory test rig.Both the simulation and experimental results basically agree well in that,the damper can effectively control the misalignment vibration of the rotor system and improves the stability of the entire rotor system.Experimental results show the amplitude of one time running speed component decreases by 30%,and the two time running speed vibration has been basically eliminated.
