Abstract

Abstract: According to the characteristic of the polygon effect in chain drive system for mining scraper conveyor, the dynamic analysis of chain drive system for scraper conveyor has been studied based on Kelvin-vogit model. Firstly, the Kelvin-vogit model which can withstand tension nor pressure has been established, and considering the polygon effect in chain drive system, the velocity signal based on the number of sprocket teeth is added to the driving sprocket. Then, the dynamic analysis is carried out for the whole model. The line velocity of the active sprocket and the velocities of four special concentrated masses are obtained. At the same time, the tensions of the four special concentrated masses are also obtained. It can be seen from the analysis results that chain model is subjected to one-side force, which is unachievable by the unprocessed Kelvin-vogit model. Meanwhile, it is verified that the polygonal effect has great influence on chain drive system's dynamics and cannot be simply ignored. This paper would provide some references on the design and analysis of scraper conveyor.
