| 摘 要： | 为研究微动对搭接结构疲劳寿命的影响,采用ABAQUS软件建立了考虑微动影响的单搭接结构有限元全局模型和子模型,运用该模型计算了接触区的应力分布.并在FRANC2D/L中把螺栓用等效的正应力和剪应力来代替,重建子模型,计算了裂纹尖端应力强度因子.最后建立了考虑微动影响下的搭接结构疲劳寿命预测模型,并将计算值与试验值进行了...

| Abstract: | A global finite element model and sub-model of single lap joint considering fretting was performed using the commercial code ABAQUS to study the influence of fretting on fatigue life of lap joint.Distribution rules of contacting stress were calculated using this model.The sub-model with the fracture mechanics code FRANC2D/L was reconstructed by substituting bolts with their equivalent loads of normal and shear tractions.Also stress intensity factors along crack lengths were calculated.At last the fatigue li... |
