Dynamiczne efekty działania obciążenia użytkowego na cięgno nośne napowietrznej kolei dwulinowej

The model of a carrying rope of a bicable ropeway system under in-service loads is introduced to analyze dynamic response of the cable during: start and steady ride of passenger carriers, an emergency stop of operating system. The pendulum model of amoving carrier is formulated to define loads acting on the cable. Equations of motion of system composed of continuous cable and a set of traveling pendulums are derived by applying Ritz approximate method and Lagrangian description of motion. Some illustrative numerical results are presented to demonstrate applicability of proposed method in an analysis of cable vibrations.
