摘　　要：某玻璃生产机械设备的弹簧在一段时间内经常发生断裂,分析断口断裂原因,并对弹簧的疲劳强度进行验证,最终结果表明:该弹簧实际工作最大拉应力和切应力大于弹簧许用拉应力和许用切应力,在循环载荷作用下发生疲劳断裂。通过优化弹簧的关键参数,提高弹簧的疲劳寿命。Targeted at the frequent spring fracture in a glass production machinery within a period of time,the paper analyzed the cause of the fracture and verified the fatigue strength of the spring.The final result shows that the maximum tension stress and shear stress of the spring at work are greater than the allowable tensile stress and shear stress of the spring,which led to fatigue fracture under cyclic loading.By optimizing the key parameters of the spring,the fatigue life of the spring is improved.
