エレベータ・ロープの振動解析について

抄録

When an elevator rope for a high-rise building is forcibly excited by long-period ground motion, rope displacement becomes large even if the ground acceleration and the buildings acceleration is small. Therefore, in order to prevent damage to the elevator, an accurate estimation of rope behavior is required. This paper introduces the following topics;(1) relation between damping factor and magnification factor/response curve of rope (string model), (2) vibration characteristics of rope (string model) with vibration suppressors, (3) estimation method of 3 parameters (equivalent flexural rigidity, viscous damping ratio, structural damping ratio) of rope (beam model).
