Abstract
In this work applications of laser Doppler vibrometers to typical problems of mechanics and possible applications in the field of ropeway transportation are discussed. Benefits have been found because of the new possibility opened up to perform, at considerable distance and without any contact, motion, and vibration measurements on components during plant operation and also on moving parts (rope, bull wheels, rotating shaft, etc.) for prototype optimization, maintenance or plant working condition monitoring with possible improvements in reliability and safety. Some case studies are presented: the application of a laser scanning vibrometer for measuring tangential movements of a rope on a sheave assembly on the chair lift ropeline, for measuring of sheave vibrations in axial direction, and for measuring flexural vibration of a portal line support.
