Dynamics Analysis of a Three-Motor-Driven Scraper Conveyor

Abstract

In response to the considerable fluctuations in motor load observed in traditional scraper conveyors employing dual-motor propulsion at both the machine’s head and tail, we propose a novel three-motor drive configuration tailored explicitly for scraper conveyor systems. Leveraging the SGZ1200/2100 model scraper conveyor as our focal point and considering real-world operating conditions, we have engineered and assessed the dynamic simulation models for both dual-motor and three-motor driven structure. This thorough analysis has yielded torque characteristic curves for each motor within both configurations under both zero-load and full-load conditions. Our findings unequivocally demonstrate that the scraper conveyor employing the three-motor drive configuration excels in mitigating torque fluctuations at the machine’s tail sprocket. This innovative design effectively minimizes torque differentials among adjacent motors, thereby furnishing invaluable data points for advancing research into the domain of multi-motor-driven scraper conveyor systems. This study serves as a promising stepping stone for future investigations in this burgeoning field of study.
