Gantry beams vibration control using cast iron cushions

The paper explores the potentials of harnessing the structural friction in the system comprising a gantry beam, cast iron cushion of requiret form and rail to the vibration control in this system. Theoretical studies yield an equivalent logarithmic decrement of vibration reduction in the system, expressed as a function of rail pressure against a crane beam through a cast iron cushion and hence the function of bolt tightness as well as other parameters. Outlined are practical applications of a cast iron cushion to vibration control of a gantry rail in a charging car installation.
