Vibration stability analysis of dual motor harmonic synchronous excitation nonlinear vibration conveyer

Abstract

To enhance the stability of a harmonic vibration synchronous conveyer, this paper establishes a nonlinear dynamical model for this kind of vibration machine, and the effects and compensation function on the stability produced by the nonlinearity of a master vibration spring have been analyzed. A small parameter perturbation method has been used to analyze the effects of a nonlinear force on the conveyer when a fluctuating impact was loaded onto the machine. The reaction between motion stability of the vibration conveyer and the synchronization of the two motors was also investigated. The results of experiments and practical applications demonstrated the correctness of the motion stability analysis of this nonlinear vibration conveyer and its application validity. In conclusion, significant reference values for design, dynamic analysis, testing, and application of the nonlinear vibration conveyer, with harmonic synchronous vibration, actuated by two motors have been achieved.

Fast Terminal Sliding Mode Control of Permanent Magnet In-Wheel Motor Based on a Fuzzy Controller

“…According to the design of the fast terminal sliding mode surface shown in (11), the full expression of FTSMC can be stated as follows:…”

“…A permanent magnet in-wheel motor (PMIWM) can be seated in the small space of the wheel of HEVs [8,9]. The performance of PMIWMs is sensitive to uncertain external factors such as temperature, vibration, magnetic saturation [10][11][12][13] and affects the comfort and safety of a vehicle. Therefore, the research on the control system of PMIWMs should take the external factors into consideration.…”

Study on stability of self-synchronous far-resonant vibrating system of two eccentric rotors considering material impact

“…The vibrating systems driven by two eccentric rotors are widely used in the industrial field, such as: vibrating screen, vibratory feeder, shakeout machine, vibration conveyor, etc. The vital factor, affecting the stability of the vibrating system, is the synchronous characteristics of two eccentric rotors, so the researches about the synchronization of eccentric rotors became a hot topic in the scientific research field in recent years [1][2][3][4][5][6][7][8][9][10][11]. In the meanwhile, vibration synchronization is the most common synchronization method, and is favored by the majority of scholars.…”

“…Further, Fang et al discussed the synchronization characteristics of two rotors vibration system, and revealed that the synchronization performance are affected by the system's parameters, coupling coefficients, and rotation direction of rotor [4,5,7]. Li et al investigated the reaction between motion stability of the vibration conveyer and the synchronization of the two motors [6]. Zhang et al studied the synchronization and stability of two unbalanced rotors separately driven by induction motors [9].…”
