摘 要: 构造刮板输送机的动力学模型及动力学微分方程。通过对刮板输送机的直接起动过程和可控起动过程的动力学仿真,研究不同工况下链条张力和速度的变化规律,通过对比二者的链条张力变化发现,可控起动工况链条张力的数值较直接起动工况可降低26�667%,采用可控起动方式有利于降低链条起动张力,提高链条的可靠性。
关 键 词: 矿山机械;刮板输送机;起动;动力学;仿真

Abstract: The dynamics model and the dynamics differential equation of scraper conveyer were established in this paper. Through dynamics simulation on direct starting process and controllable starting process of scraper conveyer, the changing law of the tension and speed of the chain under different operating performance was studied. The corresponding result is that the tension of controllable starting process is reduced 26�667% compared with that of the full�voltage starting process. It is proved that the start tension of chain can be decreased and its reliability can be increased by adopting controllable starting.
