Abstract
Vibration analysis of a gantry crane subjected to a moving trolley hoisting a swinging object is studied in this paper. The finite element method is used to model the dynamical system. Newmark's and Runge-Kutta techniques are used for direct integration of the equation of motion of the structure and the moving object respectively. The moving suspended load is modeled with a non-linear equation of motion including two degrees of freedom i.e. hoisting in conjunction with swinging. A series of numerical simulations are carried out to provide a comprehensive parametric study. The study is directed to identify dynamic characteristics of the coupled non-linear system as well as to provide sensitivity analysis with respect to design parameters. The trolley speed and acceleration as well as the hoisting pattern are the main parameters in the parametric study. Swinging angle as well as the magnitude of the frame vibration are two control parameters to evaluate the design. An optimum pattern for the motion of the load then will be presented as the outcome of the research.
