A 2:1 roping elevator system shows a complicated vibration behavior under a disturbance from the traction motor, because the disturbance does not only cause a vertical vibration to the elevator, but also induces a rotational vibration against a suspension sheave of the elevator. As the rotational vibration affects the vertical vibration of the elevator car, an analytical model of the elevator system is introduced to evaluate the relation between the vertical vibration and the rotational one. With the derived analytical model, an eigen mode analysis and a transient time analysis show the mechanism of the rotational vibration under several conditions, such as a car position and a building height.
