摘　　要：风电平台升降系统是整个平台的核心基础工作系统,连接壳是升降系统传动件与升降框架相连的关键零件,是减速器主要承力结构件。风电平台工作过程中升降系统抬升产生的抬升力对连接壳的结构变形有很大的影响,文中采用有限元方法对某型号风电升降系统减速器连接壳结构进行了设计和力学分析。在减速器承受抬升力的工况下,根据总体布置提出薄壁圆筒与方壳连接结构方案;并通过有限元分析,研究该方案结构受力的规律,结合受力分布的特点对结构进行逐步的修改;最后给出该型号连接壳结构设计方案。最终的结果表明,该型号连接壳在满足结构尺寸要求的情况下,满足了结构强度要求,保证了连接的可靠性。The lifting system of wind power platform is the basic working system of the whole platform,and the connecting shell is the key part connecting the transmission components of the lifting system with the lifting frame,and it is the main load-bearing structural part of the gearbox.During operation,the lifting force generated by the lifting system has a great influence on the structural deformation of the connecting shell.By using the finite element method,the connecting shell structure of the gearbox of a certain type of wind power lifting system was designed and mechanically analyzed.Under the working condition that the reducer bears lifting force,the connection structure scheme of thin-walled cylinder and square shell was put forward according to the overall arrangement.Through finite element analysis,the law of structure stress in this scheme was studied,and the structure was modified according to the characteristics of force distribution.Finally,the design scheme of this type of connecting shell structure was explained.The results show that this type of connecting shell can meet the structural strength requirements and ensure the reliability of the connection under the condition of meeting the structural size requirements.
