The object of regulation in the load stabilization system of the rotor of the Yurkovskii conveyer bridge

Abstract

Investigations of the operation of the automatic load stabilization system of the unit which controls the excavator section of the Yurkovskii conveyer bridge have shown that the load regulator is not operating satisfactorily. The coefficient of demand efficiency (the ratio of the maximum value to the mean) of the power expended in the motor, the forces in the guy rope suspension cables and in the metal structures of the rotor arm arehigher during automatic operation than when controlled manuaIly ( Figs. 1 and 2). This means that the regulator is causing oscillations in the system, which are dangerous because they might cause fatigue phenomena in the structure. 510
