STUDY ON CONTACT DAMAGE OF WIND POWER GEAR BASED ON CONFIGURATIONAL FORCE THEORY
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.
