摘　　要：为了改进刮板输送机铲板槽帮的设计、提高设备可靠性,建立了铲板槽帮端部及哑铃销的三维几何模型,并针对模型的机械强度进行了有限元分析。分析得到了铲板槽帮端部的应力分布情况,并算出了铲板槽帮端部的安全系数。In order to improve the design and reliability of scraper conveyor rump pan, 3D model for end region of scraper conveyor rump pan and dumbbell pin is created, and a finite element analysis is operated for its mechanical strength. The stress distribution is obtained for end region of scraper conveyor rump pan.
