“…4 Linear Analysis of Simplified Model The overall system, including the mechanical part, induction motors and the controller is a highly nonlinear complex system of the high order (cf. (Galitskaya and Tomchina, 2012;Fradkov et al, 2013;Tomchina, 2018;Tomchina, 2020;Fradkov et al, 2021)). However, as stated in (Fradkov et al, 2021), in medium and high frequency ranges, the so-called the averaging property, which is widely exploited in the vibrational mechanics is valid.…”

In the paper the problem of multiple controlled synchronization of a pair of unbalanced rotors is considered. A new bidirectional control law is proposed for multiple synchronization of rotors. A linear analysis of the dynamics of a simplified system model is presented, demonstrating the control system robustness with respect to the parameters of the vibration machine and controller. The main part of the paper is devoted to the description of the experimental results obtained at the Multiresonance Mechatronic Laboratory Setup, demonstrating the efficiency of the proposed approach and revealing its application scope.

“…The use of the most effective resonance modes is sophisticated by their instability, which appears even with minor changes in the system parameters, as well as due to nonlinearities arising from the working element interaction with the processed material and/or with a vibration drive of limited power [Gouskov and Panovko, 2012;Cveticanin et al, 2017;Nayfeh and Mook, 1995;Sinha et al, 2020;Yaroshevich, 2020]. All this increases the complexity of maintaining near resonance modes and leads to the need to use systems for controlling the electric motors rotational speed [Fradkov et al, 2013;Panovko et al, 2015].…”

The article analyzes the possibility of using nonlinear elastic elements as a suspension of the working element of resonant vibrating machines with two unbalance vibration exciters is analyzed. The elastic characteristic of the suspension is described by an exponential law, which ensures that the natural frequency remains unchanged regardless of the system mass. Static characteristics of the vibration exciter motors are taken into account. A system of differential equations describing movement of the system depending on the processed material mass is obtained. Amplitude-frequency characteristics depending on the power supply voltage, as well as on the debalance rotational speed are obtained for different values of material mass. The stability of the obtained periodic solutions is analyzed. The constancy of resonant amplitude and frequency of the working element vibrations at various values of material mass is shown. The results obtained confirm the advisability of using an equalfrequency suspension of the working element for resonant vibrating machines.

“…However, research on improving the exciting force and amplitude of a shale shaker to enhance its load conditions and increase its processing capacity is limited. Most existing synchronization theories are concerned with the following aspects: selfsynchronization and control synchronization of rigid drive vibration systems with single and double vibro-bodies [14][15][16], self-synchronization of rigid drive vibration systems with parallel and cross axes [17][18][19][20], and self-synchronization of vibration systems flexibly driven by two motors in common axes [21]. However, related investigations on the spatial vibration and synchronization of vibration systems flexibly driven by one motor on both sides are few.…”

A dynamic model of a vibration system, in which eccentric rotors are driven by one motor with two flexible couplings, is developed in this study. The Lagrange equation is used to analyze the dynamic behavior of the vibration system. Synchronization theory and its motion law are investigated using Hamilton’s principle, and the validity of the theory is proven through numerical simulation and experimentation. Results show that the system has two synchronous motions, namely, 0 and π phases. When the torsional stiffness difference between two flexible couplings on both sides of the motor or the resistance moment difference between two eccentric rotors increases, the eccentric rotors maintain the synchronization and stability of the vibration system by adjusting its phase difference. Synchronization theory and the analysis method of the flexible-drive vibration system are extended in this study. Moreover, the synchronous motion law of the vibration system based on bilateral flexible drive by one motor is revealed to provide guidance for the development of high-performance vibrating machines.
