摘　　要：风电机组齿轮箱长期处在随机风载等复杂环境下,其齿轮接触疲劳成为限制风电机组装备稳定性与可靠性的关键因素,进行齿轮接触损伤演化机制研究面临着应力状态复杂、损伤各向异性及失效建模困难等难点。材料构型力理论可以描述缺陷构型变化对材料自由能的影响,可用来预测材料的损伤和失效行为。基于构型力理论建立齿轮接触损伤模型,选取齿轮接触承载关键区域进行齿轮接触界面应力场仿真分析,模拟在接触载荷作用下齿轮接触损伤演化过程。结果表明,构型力理论损伤模型可以有效模拟齿轮接触损伤现象,解释齿面点蚀和剥落,对准确预测齿轮接触疲劳寿命具有指导意义。The gearbox of wind turbine is in the complex environment such as random wind load for a long time,and the gear contact fatigue becomes a key factor limiting the stability and reliability of wind turbine equipment.The research on the gear contact damage evolution mechanism is faced with difficulties such as complex stress states,damage anisotropy and failure modeling.Material configurational force theory can describe the effect of defect configurational change on the free energy of materials and can be used to predict the damage and failure behavior of materials.A wind turbine gear contact damage model was constructed based on this theory.The gear contact interface stress field simulation analysis was carried out for the key bearing area of gear contact,and the gear contact damage evolution process under contact load was simulated.The results show that the configurational force theory damage model can effectively simulate the contact damage phenomenon of gear and explain the pitting and spalling of gear surfaces.It has significance to predict contact fatigue life of gears accurately.
