本文基于LZ55-3.0MW型叶片，用有限元软件ABAQUS建立风机叶片根部T型螺栓连接的有限元模型，应用有限元接触分析方法，研究了在轴向载荷作用下，叶根玻璃钢和T型螺栓连接的受力变形，同时对模型进行强度校核和能量分析，为叶片根部螺栓连接的设计提供合理的指导。%Based on LZ55-3.0MW blade , this paper presents the finite model of the root T-type bolts connection for wind turbine. This simulation , by means of the finite element contact analysis method , investigates the loading deformation behavior of the blade root and T-bolt connections under axial loads , and meanwhile through analyzing the strength and energy of the model to provide reasonable guidance for the design of the blade root connection .
