Kinetic Analysis of Four-link Gantry Crane Hoisting System

This paper establishes a flexible dynamics model of MQ2533 portal crane boom system. In the premise of ignoring control system, this paper analysis the mechanical dynamics of boom hoisting system. Simulation results show that: Dynamics response of the hoisting boom system have great fluctuation when excluding the control effects, this paper provide a theoretical basis for crane hoisting system to optimize control strategies, which committed to improve their performance and ensure safety, reliability and economy.
