Abstract：[Objective]To address the issues of crawling and poor motion stability in low-speed and heavy-duty conveyor chain transmissions,a dynamic model of the above conveyor chain transmissions was established based on multi-body dynamic theory,and the research on dynamic characteristics was carried out,aiming to provide guidance for enhancing the stability of such conveyor chain transmission systems.[Methods]By considering the structural characteristics of low-speed and heavy-duty conveyor chain transmission systems and the effects of conveying loads,the mechanical properties of the conveyor chain nodes were simulated using Hooke's law,and a dynamic model with 107 degrees of freedom of the conveyor chain was constructed.The modal superposition method was adopted to solve the dynamic model,the dynamic characteristics of the low-speed and heavy-load conveyor chain were obtained,and the influence laws of the slack side sag and the tight side friction force of the conveyor chain on the transmission speed variation were studied.[Results]The results show that reducing the slack side sag and decreasing the friction coefficient between the conveyor and the guide rail can effectively reduce the occurrence of the crawling phenomenon in conveyor chain transmission and improve the motion stability of the conveyor chain transmission systems.
