摘要
为使前后风轮间流场干涉影响降低,双风轮风电机组传动链具有跨距长、支撑点多的特性,导致双风轮风电机组传动链在长跨距柔性主机架支撑下具有复杂的载荷特性.建立考虑主机架柔性的某型双风轮风电机组传动链动力学模型,分析齿轮与主机架结构强度.结果表明:各级齿轮接触强度、弯曲强度以及主机架强度均满足设计要求;主机架支撑变形有助于协调各构件之间的相对变形,适量减小主机架柔性有助于改善传动链承载时主轴轴承之间的轴线不对中情况.
Abstract
To reduce the interference effects of the flow field between the upwind and downwind rotor,the double-rotor wind turbine drivetrain is featured a long span and many support points,causing complex load characteristics of the double-rotor wind turbine drivetrain supported by a long-span and flexible mainframe.In the work,a dynamic model of a type of double-rotor wind turbine drivetrain is established considering the mainframe's flexibility.The structural strength of gears and the mainframe is analyzed.The results show that the contact strength and bending strength of gears as well as the structural strength of the mainframe satisfy the design requirement.The supporting deformation of the mainframe is beneficial to comply with the relative deformations between components.Reducing the mainframe's flexibility appropriately is beneficial to reduce the axial misalignments between upwind and downwind main shaft bearings when the drivetrain is loaded.
