摘　　要：双列圆锥滚子轴承对于半直驱式风力发电机组来说是其运转的主要轴承之一。其性能的优劣直接关系到其使用寿命。目前对双列圆锥滚子轴承的研究主要集中在单体轴承上,较少综合考虑多部件的轴承系统研究。对此提出了一种考虑多部件的刚柔混合多体力学分析模型,该模型可用于系统模型的分析研究。结果表明:接触载荷与理论计算接触载荷呈现相似的变化趋势,左列滚子沿素线方向上的接触应力分布更加均匀,滚子零度附近只有一列轴承承载;接触应力仿真结果与理论计算结果误差为4.56%,在误差允许的范围内,因此对提出的刚柔混合多体力学系统模型进行接触应力分析是可行的。Double-row tapered roller bearings are one of the main bearings for semi-direct drive wind turbines.Its performance is directly related to its service life.At present,the research of double-row tapered roller bearings is mainly focused on single bearing,and the research of multi-component bearing system is rarely considered comprehensively.In this paper,a rigid-flexible hybrid multi-force analysis model considering multiple components is proposed,which can be used for the analysis and research of system models.The results show that the contact load is similar to the theoretical contact load.The contact stress distribution of the left row roller along the prime line is more uniform,and there is only one row bearing near zero of the roller.The error between the simulation results and the theoretical calculation results is 4.56%,which is within the allowable range of error,so it is feasible to analyze the contact stress of the proposed rigid-flexible mixed multi-mechanical system model.
