Abstract

Swing of a ropeway carrier is easily caused by wind and it is very difficult to reduce. In this paper, several types of dynamic vibration absorbers for a ropeway carrier are analyzed theoretically, and a general theory is formulated. A method of optimum tuning is obtained and the index (equivalent mass ratio) which indicates the effect of the absorber is defined. When the dynamic vibration absorber is located at the center of oscillation, swing is not reduced at all. The center of oscillation is the point that is located at the distance of equivalent length of the pendulum from the center of suspension (fulcrum). The absorber should be located as far as possible from the center of oscillation.
