Abstract

In this paper we have studied the characteristics of the vibration of winding ropes in vertical shafts when the drums are braked in an emergency, measuring the vibration and analying the measured results by the theoretical methods published in our former paper.<BR>Some results we have obtained through our researches are as follows;<BR>1) The maximum vibration of a winding rope in a vertical shaft when the drum is braked in an emergency can safely be estimated to be 1.3 times as large as the maximum acceleration of the winding drum.<BR>2) The shock absorber is hardly effective for reducing the vibration of a winding rope in an emergency braking.<BR>3) We find that the length of a winding rope has nothing to do with its vibration in a shaft.
