Vibration Isolation Technique Application and Prospect in Power Apparatus

Except enhancing traditional anti-seismic design,it is necessary to enhance development and application of power equipment vibration isolation techniques. Taking an engineering practice in which the technique is used for a certain machine rotation vibration control as an example,the vibration isolator stiffness,damping and geometric size are decided based on isolator configuration principles. The maximum vibration linear displacement and isolation efficiency of spring-damping vibration isolation system are calculated by the self-composed program. Finally,the paper gives a forecast of its application in turbine-generator foundation and substation.
