In this report, the natural frequencies, dynamic tensions and other characteristic values are derived for the winding rope with tail rope at work, and the analytical results are compared with some measured data in rope guided winding shafts.
Some results obtained are as follows;
(1) The portion of the winding rope between driving sheave and head sheave must be included into consideration to thel ongitudinal vibration of the winding rope.
(2) The natural frequency of the longitudinal vibration of the winding rope can not be calculated unless the weight of the tail rope is smaller than the weight of the cage, in which the weight of the tail rope may be an additional weight of the cage.
(3) The 2nd mode amplitude of the longitudinal vibration of the winding rope with tail rope is greater than the 1st mode amplitude, when the cage is disturbed near the pit mouth.
