摘要: 针对JAT610织机综框边杆的非正常断裂,用ANSYS有限元软件进行应力分析,结合应力实测的结果,对边杆的疲劳寿命进行分析计算,找到了疲劳寿命不足的原因并对结构进行了改进以延长结构的疲劳寿命,经企业实际应用,取得了良好的效果。通过分析指出,高速运转机构的应力集中导致的疲劳对机构的寿命产生很大影响,减少最大应力和应力幅度能有效地延长机构的寿命。

Abstract: Because of the deviant fracture on lateral supports of JAT610 loom,the stress of the bar was studied by FEM software ANSYS,combining the stress result of actual measure in facture,the fatigue life of the bar was calculated. The reason that the fatigue life of the bar was too short was found,and the shape was improved to extend the fatigue life. The analysis shows that the stress convergence in high-speed machine would cause the machine fatigue and influence the life of the machine, the decrease of the maximal stress and range of stress in machine can extend the fatigue life of machine availability.
