Random wind speed causes frequent load fluctuations in the wind turbine gearbox transmission system, resulting in complex structural deformations and gear deflections, which aggravate the risk of gear contact failure. A novel method to improve the fatigue performance of wind turbine gearbox transmission systems considering the stochastic uncertainty of environmental parameters is proposed. The mapping relationship among wind turbulence intensity-gear modification parameter-gear long-term contact fatigue damage is reconstructed by the surrogate model method based on the dynamic model of the wind turbine transmission system considering global loads. And then, a multi-stage gear modification parameter optimization function considering the probability distribution of wind speed is established and the optimizing fatigue performance is compared. The results show that the long-term gear contact fatigue damage value of the low-speed stage sun gear is more than 0.7, which is one of the weak parts of the high-reliability design of the wind turbine gearbox transmission system. The long-term gear contact fatigue damage values of optimizing gears have been reduced significantly, in which the low-speed stage sun gear has been reduced by 11.37%, so the fatigue performance has been improved significantly. |
