ASSURANCE OF SELF-SYNCHRONIZATION OF UNBALANCE VIBRATION EXCITERS OF TRANSPORTER EQUIPMENT OF PIT DUMPER
The description of hydraulically operated vibrational dumper developed at Institute of Mining SB RAS for rock mass transloading from trucks into dump is given. The attention to the construction of vibration transporter equipment whose attachment is represented with metal sheet with low bending stiffness is paid. Two inertial vibration exciters have been set for assurance of uniform vibration field throughout transporting equipment. The procedure and results of the tests of dynamic of flexible attachment equipped with two unbalance sources of oscillations are shown. Allowable mismatch of partial frequency, at which in-synch working mode of vibration exciters is saved, is established. The influence of constructive parameters of attachment on stability of in-synch mode is determined. The description of experimental prototype of vibration dumper is given. Results of tests of the dumper has proved the efficiency of using such equipment for working at truck dumps of mining enterprises.
