摘　　要：转子不对中会造成运行故障和载荷参数改变.通过传递矩阵法,采用锥形类轴单元处理锥形转子,建立不对中风力发电机锥形转子系统的模型,并计算其特征值.分析锥形轴段单元数对其特征值的影响,讨论轴向载荷和扭矩载荷参数对风力发电机锥形转子系统特征值的影响.为风力发电机锥形转子系统不对中故障研究提供指导.Misalignment of the rotor can cause operational failures and changes in load parameters.The eigenvalues of the rotor system of the misaligned wind turbine are calculated by the transfer matrix method and the conical rotor of the wind turbine is built by a cone-like shaft unit.The number of shaft segments is determined,and the eigenvalues of the conical rotor system of the wind turbine are discussed from load parameters,which can provide guidance for the study of misalignment of wind turbine cone rotor systems.

关 键 词：风力发电机锥形转子系统 传递矩阵法 不对中故障 特征值
