Experimental researches of dynamics of rope of one-end lift

Abstract

Established method for determining the stress-strain state of structural elements – method
electrical tensometry where sensitive to deformation element is a strain gauge attached on the
respective scheme to the recording equipment.
Describes an experimental model one-end lift installation consisting of a hoist, hoisting
rope, cage models with load, damping device, a measuring plate with active strain gauges and
ADC/DAC ZET 210 module, a recording stress-strain state of the object.
Obtained results of experimental studies that suggest about the accuracy of laws, obtained
theoretically, and the proposed construction of a damping device with rubber elements is effective.
Coefficient of dynamic rope considering only dissipative forces rope is in the range 1,94 application device
reduces the dynamic damping ratio to an average of 1,345, depending on the weight of the cargo terminal.
