摘要
风电机组叶轮承受风载产生的推力和弯矩等非扭矩载荷传递到齿轮箱内部,会引起关键部件振动加剧、动载增大,将加速齿轮、轴承等部件的过早失效.本文针对某5 MW风电齿轮传动系统,考虑行星架和太阳轮轴的柔性,计算了各对齿轮间的啮合刚度和阻尼以及轴承的支承刚度,采用ADAMS软件建立其刚柔耦合动力学模型,分析了非扭转载荷对关键部件振动和动载荷特性的影响,结合理论分析与对比验证,掌握了非扭矩载荷引起低、中和高速级齿轮振动位移和动态啮合力以及轴承动载增大的变化规律,将为齿轮传动系统动态性能评估及其可靠性优化设计提供重要的理论依据.
The wind load produce non-torque loads,including thrust and bending,which transmit to the gear transmission system and bring additional vibration displacement and dynamic loads to the gears and the bearings,which accelerate the premature failure of the components.A 5 MW gear transmission system of the wind turbine was taken as an example,gear mesh stiffness and damping and the stiffness of each bearing were analyzed,its rigid-flexible coupling dynamic model was built within the software ADAMS,in which the flexibility of the planet carrier and the sun gear shaft was considered.The effects of the non-torque loads on the dynamic response characteristics of the gear transmission system were analyzed.The simulation results were agreed well with theoretical formula calculation results.The relationship between the non-torque loads and the increase status of the vibration displacements and the dynamic meshing forces of the gears and the dynamic loads of the bearings are obtained.This study can provide theoretical bases for dynamic performance evaluation and optimized reliability design of wind turbine gear transmission system.
