摘要

了解刮板链轮-尾鼓链路的相互作用，对提高综采设备中间刮板输送系统的运输效率和使用寿命具有重要意义。刮板链的内部张力、运行阻力和多接触面载荷的动态特性是研究的理论基础。首先，提出了一种获取周期性循环动态载荷历史的方法，然后利用RecurDyn和仿真结构建立了连续采煤机单链刮板输送机的模型。最后，确定了输送倾角、套筒刮板链运行速度等参数对输送系统可靠运行的影响。结果表明，当输送角度为12°时，刮板输送系统运行稳定，多刚体之间的冲击较小。随着链条速度从0.85m/s增加到2.4m/s，输送系统的磨损逐渐增加，上链板2、上链板3和下链板3的接触载荷分布严重磨损。

Study on multibody contact load distribution characteristics of scraper conveying system of continuous miner

Understanding the interaction of scraper chain-sprocket-tail drum-chain path is of great significance to improve the transportation efficiency and service life of the intermediate scraper conveying system of fully mechanized excavation equipment. The dynamic characteristics of the internal tension, running resistance and multi-contact interface load of the scraper chain are the theoretical basis of the research. Firstly, a method for obtaining periodic cyclic dynamic load history is proposed, and then the model of single chain scraper conveyor for continuous shearer is constructed by using RecurDyn and simulation structure. Finally, the influence of parameters such as conveying inclination angle and running speed of sleeve scraper chain on the reliable operation of conveying system is determined. The results show that when the conveying angle is 12 °, the scraper conveying system runs stably and the impact between multi-rigid bodies is small. As the chain speed increases from 0.85 m / s to 2.4 m / s, the wear of the conveying system gradually increases, and the contact load distribution of the upper chain plate 2, the upper chain plate 3 and the lower chain plate 3 is seriously worn.
