Abstract:As an important aspect for dynamic design, the lateral vibration characteristics of friction hoist directly affect the friction hoist security work. To further study the relationship between frictional lateral vibration and related factors, the theory of elasticity mechanics was used to build the distributing theoretic model of coupled ropecage vibration for friction hoisting system. Finite element method was used to verify the feasibility and effectiveness of the proposed model. The causes and effects of abnormal vibration and dynamic instability during the upgrade hoisting were analyzed. The results show that linear density of wire rope, operating load, hoisting speed have significant impact on lateral vibration, while the contact stiffness of container and can road has slight effect.
