传动故障载荷下圆环链动力学特性分析
摘要
针对刮板输送机卡链故障下的突变载荷对圆环链的冲击,以Φ18 mm×64 mm C级矿用圆环链为研究对象,运用ANSYS/LS-DYNA有限元软件对卡链状态下的圆环链做非线性接触动力学分析,得到圆环链加速度、速度、能量、接触力的变化规律以及圆环链磨损的主要位置,为研究矿用圆环链传动故障状态下的损伤机理提供了理论依据。
Abstract
Aiming at the transient impact of the abrupt load on the ring chain under the fault of the scraper conveyor chain jammed,taking the Φ18 mm×64 mm C class mining ring chain as the research object,by using the ANSYS/LS-DYNA finite element software,the nonlinear chain contact dynamics analysis under the condition of the chain jammed is performed,the change law of the acceleration,velocity,energy and contact force of the ring chain and the main position of the ring chain damage are obtained. A theoretical basis for researching the damage mechanism of mining ring chain transmission under the condition of fault is provided.
