摘　　要：为分析堆料机悬臂皮带机驱动联轴器断裂损坏的原因,采用应力分析与疲劳强度相结合的计算模型,利用有限元分析软件对联轴器进行应力分析,并对疲劳许用应力进行校核。分析结果表明:改进后的结构可以有效降低部件的最大应力,提高结构疲劳强度,保证设备的安全运行。A computational model is established by the stress analysis and fatigue strength to analyze the reasons for the fracture and damage of the cantilever belt conveyor driving coupling of stocker. The stress analysis of the coupler is carried out and allowable fatigue stress is checked by the finite element analysis software. It is shown that the improved structure can reduce the maximum stress of the components effectively, improve the fatigue strength of the structure and guarantee the safe and stable operation of the equipment.
