摘要

大功率风电齿轮箱为风力发电机组关键部件之一，其工作特性对风电机组稳定运行具重要影响。论文针对某大功率风电齿轮箱参数及工况，考虑斜齿轮副时变啮合刚度和传递误差激励,建立齿轮箱传动系统子结构模型；基于均匀弯曲Timoshenko理论，建立齿轮箱箱体子结构模型；根据传动子结构和箱体子结构系统变形协调条件，建立大功率风电齿轮箱系统耦合动力学模型，对系统振动响应进行计算分析。研究表明，各级齿轮啮合激起结构响应频率，结构响应频率与系统齿轮啮合频率未发生共振；在系统振动加速度响应频率成分中，除三级齿轮传动啮合频率外，存在调频现象，并将研究结果与试验结果进行对比分析。

Abstract

A high power wind turbine gearbox is one of the key parts in wind turbine.The stability performance of the wind turbine is influenced by the characteristics of the wind turbine gearbox.According to the parameters and conditions of a typical wind turbine gearbox,the sub-structure model of the wind turbine gearbox transmission system was built considering the time-varying mesh stiffness and transmission errors.Base on the theory of uniform bend Timoshenko bean and cantilever beam,the sub-structure model of the housing structure system was established.On the strength of the deformation compatible conditions for the models of the transmission and box sub-structure,a coupled dynamic model of high power wind turbine gearbox was built and the vibration responses of the coupled system was calculated.The results show that the structure frequencies of the system were excited by the gear meshing of the different stages in the coupled system.The resonance does not occur between the structure response and gear mesh frequencies.The vibration acceleration frequency of the system composed of the frequency modulations except for the gear mesh frequencies of the system.Finally,the analysis results were compared with the results from the rig test.
