摘　　要：针对传统风力机叶片举升装置存在重心调节效果较差和可靠性不佳的难题,基于水平拉杆式结构设计了一种举升装置。以运载某型号风力机叶片为例,对该装置进行重心计算、受力分析、仿真研究及现场试运行,结果表明,此装置整体重心的最大偏移量为0.49 m,小于半挂车的半轮距,不易引起翻车事故。关键构件的受力也较为平稳,且仿真的最大应力小于许用应力,满足强度设计要求。该装置成功应用于风力机叶片运输的实例,进一步验证了设计的正确性和结构的可靠性。Since the traditional wind turbine’s blade-lifting mechanism has a poor center of gravity adjustment effect and poor reliability,in this article a lifting mechanism is designed based on the horizontal tie-rod structure.With a type of wind turbine’s blade as an example,the center of gravity calculation,force analysis,simulation research,and field trial operation of the mechanism are carried out.The results show that maximum deviation of the mechanism’s overall gravity center is 0.49 m,which is less than a semi-trailer’s half-track,unlikely to cause a rollover accident.The stress of the key components is also relatively stable,and the simulated maximum stress is less than its allowable counterpart,which meets the requirement of strength design.This mechanism is successfully applied to the example of transportation of the wind-turbine’s blade,which has further verified that the design is correct and the structure is reliable.
