摘要
针对现有刮板输送机链传动系统启动时振动、冲击大以及链环和链轮使用中磨损严重的问题,建立了链传动系统啮合的数学模型,利用LS-DYNA仿真分析软件对链传动过程链条和链轮啮合时的动力学特性进行了分析,确定了刮板输送机链传动系统工作时的应力和应变规律,为提升链传动系统工作可靠性和使用寿命提供了理论支持,具有十分显著的应用效果和推广价值。
Aiming at the problems of vibration and shock when the chain drive system of the existing scraper conveyor starts, and the serious wear and tear in the use of chain link and sprocket, a mathematical model of the meshing of chain transmission system is established. The dynamic characteristics of chain and sprocket in chain drive process are analyzed by LS-DYNA simulation analysis software, and the stress and strain law of chain drive system of scraper conveyor are determined. It provides theoretical support for improving the working reliability and service life of chain drive system, and has remarkable application effect and popularization value.
