Creation and verification of spatial mathematical model of vibrating machine with two self-synchronizing unbalanced exciters

Vibration technological machines with self-synchronized unbalanced vibration exciters (vibrating conveyors, vibrating screens, vibrating crushers, etc.) are widely used in modern industry. Despite drive construction simplicity throughout exploitation of such machines a number of nonlinear dynamics e...
