During a normal work cycle, stacker cranes can exhibit large vibration amplitude due to the impulsiveness of the loads to which they are subjected. In order to control and reduce these vibrations, a simple lumped parameter (LP) model of a stacker cranes has been developed. The parameters of the LP have been estimated by means of a more detailed finite element model. The LP model has been used in order to evaluate the effectiveness of a tuned mass damper (TMD) for vibration suppression. The TMD has been tuned by means of the model results. Eventually, a new prototype of a stacker crane has been designed including the TMA.

Abstract
During a normal work cycle, stacker cranes can exhibit large vibration amplitude due to the impulsiveness of the loads to which they are subjected. In order to control and reduce these vibrations, a simple lumped parameter (LP) model of a stacker cranes has been developed. The parameters of the LP have been estimated by means of a more detailed finite element model. The LP model has been used in order to evaluate the effectiveness of a tuned mass damper (TMD) for vibration suppression. The TMD has been tuned by means of the model results. Eventually, a new prototype of a stacker crane has been designed including the TMA.File in questo prodotto:
