“…Based on vibration mechanics theory, two resonance points should be observed in two DOF system under the identical frequency excitation, and four resonance points under two different frequency excitations. The first-order natural frequency v n1 and second-order natural frequency v n2 are calculated by equation (15), which are consistent with the resonant frequencies of the low-frequency motor in Figure 2.…”

Vibrating screen is the pivotal equipment of solid control in drilling mud purification system. With the continuous upgrading of rapid drilling technology, the conventional single-body vibrating screen with the same-frequency excitation is difficult to satisfy the needs of current drilling operations. Therefore, a newly dual-body vibration absorption system model with double-frequency excitation is proposed to improve the mechanical performance of screening equipment. To grasp the dynamic characteristics of the vibration system, the synchronization mechanism and stability criterion are theoretically studied by modified small parameter average method and Poincare-Lyapunov method. Meanwhile, the vibration absorption ability, coupling torque and synchronization state of the system are numerically discussed. Lastly, the electromechanical coupling model of system is established by Runge-Kutta method to verify the reliability of theoretical analysis and numerical calculation. According to the results of research, the synchronous characteristics are mainly determined by the installation position of motors and the mass ratio of eccentric rotors. Besides, the synchronization ability between identical-frequency motors is stronger than different frequency motors. The present work can provide theoretical direction for designing of new screening equipment.

“…Peng et al investigated the stability and synchronization conditions of the anti-resonance system with three exciters and a secondary vibration isolation system with two exciters [28,29]. Finally, Zou et al studied the multiplefrequency synchronization of two vibrating motors and proposed a controlled system for two eccentric rotors actuated with a double-frequency [30,31]. The scholars mentioned above at home and abroad have conducted many investigations regarding the problem of multiple motors' synchronous motion of vibrating screens via theoretical modeling, simulation analysis, and vibration testing.…”

The vibrating screen with statically indeterminate mesh beam structure (VSSIMBS) is a novel type of large vibrating screen, which is widely used in coal preparation plants due to its high strength and processing capacity. In this study, the VSSIMBS motion differential equations were obtained via on Lagrange equation, and the dynamic vibration system model was established. The eccentric block force conditions during the operation were analyzed, and the stable vibrating screen operational conditions were obtained. The electromechanical coupling simulation model of VSSIMBS was built in Simulink, allowing frequency control and vibration synchronization experiments. Experimental frequency control results have shown that when the output characteristics of both motors are either the same or similar, synchronous movement can be achieved. Regarding vibration synchronization, experiment results have shown that when two motors are in synchronous motion, and the power supply of one motor is cut off, they still can operate synchronously. Thus, the experimental results obtained in this study provide a theoretical reference for improving the motion stability of large vibrating screens.

“…From the recently published works concerning the synchronization of vibrators (Chen et al, 2016; Cieplok and Wojcik, 2020; Lyan et al, 2021; Zhang 2020; Zhang et al, 2020, 2021; Zhao et al, 2010), the dynamic model become more closely related to the actual vibrating machines including vibrating conveyor, vibrating screen, and vibrating mill, and so on. Besides, although the control synchronization (Fang et al, 2021; Fradkov et al, 2021; Huang et al, 2021; Jia et al, 2019; Li et al, 2022), multiple-frequency synchronization (Li and Chen, 2019; Zou et al, 2021), and composite synchronization (Kong and Wen, 2018) have also been investigated, the self-synchronization theory was still the most typical synchronization strategy used in engineering. With the development of synchronization theory, some scholars also paid attentions to other problems in designing vibrating machines, such as dynamic adjustment of vibration direction angle for the vibrating screen (Chen et al, 2020), and two-stage vibration isolation of vibratory shake-out conveyor (Fiebig and Wrobel, 2017).…”

Due to complex dynamic coupling relationships in the system, the research that couples pendulum and vibrators in the same system is rarely found. Especially in the vibrating system with spatial motion, the theoretical derivation may be too complex to be easy to implement. In this paper, we present a vibrator-pendulum coupling system with spatial motion characteristics; here, the pendulum is driven by the two vibrators mounted on it. The synchronization of the vibrators and the motion characteristics of the system are studied via theory, numeric, and experiment. In theory, the synchronization and stability criteria of the two vibrators are deduced. According to the theoretical results, some numerical qualitative analyses are given to further reveal the synchronous stable states and spatial motion characteristics of the system. The validity of the theoretical methods and the correctness of the numerical qualitative results are examined by simulation and experiment. Taking the pendulum as the working rigid frame, the proposed dynamic model and research results can be applied to design a new kind of vibrating jaw crusher with spatial motion characteristics.
