Differential equations of motion of a vibration machine together with its inertial unbalance drive in the form of two rotating eccentrics are considered. The general solution of the equations of motion is obtained in the first approximation under the conditions of transition through the resonance zone. The expressions for the maximum resonant amplitudes and the corresponding values of the phase and rotational speed of the inertial vibrator unbalances are found. The analysis of the obtained expressions during the acceleration and run-out of the vibratory drive of the machine is given.
