dynamic responses of a gantry crane system due to a moving body considered as moving ócillator pdf

  • Jan 01, 2015 · The general approach in moving load problems at cranes is also used here, thus the system of the gantry crane (Fig. 1a) is divided into two parts: the framework (structure) and the moving system. The framework is a 2D discrete model consisted of top beam with length L , pier leg with height H and sheer leg with height h .

  • Dynamic responses of a gantry crane system due to a moving

    This paper discusses a combined finite element and analytical method for obtaining transverse and longitudinal vibrations of a gantry crane system subjected to an elastically suspended moving body. The two-dimensional inertial effects of the moving body are included in derivation of differential equation of motion for the system.

  • Jul 09, 2020 · In this paper, a novel moving load model for 2D crane systems of which the trolley has two axles is proposed. Based on this model, the dynamics of a 2D gantry crane, which is modelled as a simply supported Euler–Bernoulli beam carrying a two-axle trolley from which a single-pendulum payload is suspended, is studied. The proposed model was verified by comparing with two models in

  • Jun 24, 2019 · An overhead crane with a flexible cable is an underactuated system; the vibration of the crane’s beam and the residual swinging of the payloads cause fatigue in the crane and affect the precise positioning of the payloads. In this paper, the coupling system of an overhead crane was simplified to that of a moving mass with pendulum swing passing beam model. The differential equation

  • The dynamic response of such a coupled system is quite different from that of the beam structure subject to moving loads or moving oscillators. The dynamic interactions between the beam and moving rigid bodies are complicated, mainly because of the time-varying number and locations of contact points between the beam and bodies.
