Abstract :
The vibrational motion of an elastic beam fixed on a moving cart and carrying a moving mass was investigated. The equations of motion which describes the total dynamics of the beam-mass-cart system were derived and the coupled dynamic equations were solved by unconstrained modal analysis. In modal analysis, the exact normal mode solutions corresponding to the eigenfrequencies for the position of the moving mass and the ratios of the weight of the beam-mass-cart system were used. Proper transformations of the time solutions between the normal modes for a position and those for the next position of the moving mass were also adopted. Numerical simulations were carried out to obtain the open-loop responses of the system in tracking the pre-designed path of the moving mass
