| Abstract: | In this paper the tower-shaped rope guides and rubbing multistringed hoist system is simplified. The mechanical and mathematical model ol the multi-degree lateral vibration system has been established by lumped-mass method and the equation of motion. The numerical calculation and simulation tea of lateral vibration have been done.The system frequency has been analzed when the hammer weight and hoist height change. |
