We proposed new vibration isolation system transmitted from the elevator traction machine to the adjacent room. This system is constructed with small active mass damper (AMD) attaching on the machine bed of a traction machine. For getting more performance, we evaluated two modeling method for obtaining numerical model of vibration transfer system of a traction machine. One is the method of using experimental modal analysis, and other is the system identification method. As a result, we could get more precise numerical model from system identification method. Based on the obtained numerical model, we designed system controller using LQ control method and investigated the performance of this system with the elevator in our test tower. We could attain to reduce the transmitted vibration to the adjacent room from the traction machine for about 50% or more.
