建立SGZ764/400刮板输送机圆环链的有限元模型,以卡链故障状态下的圆环链为研究对象,分析圆环链的速度响应特性和主应力响应特性,得到卡链发生时圆环链的速度和应力变化情况,结合上述理论分析结果提出了相应的改进措施。
The finite element model of the circular chain of SGZ764 / 400 scraper conveyor was established. The circular chain under the fault of the card chain was taken as the research object. The velocity response and the principal stress response characteristics of the circular chain were analyzed. The chain speed and stress changes, combined with the above theoretical analysis of the corresponding improvements proposed.
