INSTALLATION FOR INVESTIGATION OF FREE VIBRATIONS OF LOAD SUSPENDED ON SPRING PLACED VERTICALLY

摘要

Installation for investigation of free vibrations of load suspended on arranged in vertical position spring has: basis with controlled stems-screws; vertical rod fixed on the basis, with holder that is displaced by beam and is fixed on needed height; load suspended on placed vertically spring; electric magnet. Electric magnet that holds the load in initial state is fixed in front of the beam at one end of the base, the upper end of the spring is fixed on holder, on the load plate-indicator of vibration of load is fixed, on additional rod fixed at the other end of the basis quick register of image is installed with objective at level of plate-indicator after which on the rod with holder in vertical position coordinate net is placed, with vertical and horizontal coordinates, image register through quick-acting interface is connected to computer..
