摘　　要：主轴作为摩天轮最重要的零部件之一,几乎承载着整个运行结构的全部重量,主轴是否满足强度要求,对摩天轮的安全运行起着至关重要的作用。摩天轮主轴上不仅有弯曲正应力,还有弯曲切应力。本文将从力学理论方面讲解弯曲切应力的推导过程,即利用分离体轴向静力平衡推导纵向剖面切应力,利用切应力互等定理推导出轴的弯曲切应力求解公式,并通过ANSYS Workbench仿真平台,建立摩天轮主轴的有限元模型,进行结构有限元分析,获取主轴危险截面的弯曲切应力和弯曲正应力,得到仿真结果与理论计算结果比较,表明计算结果的可靠性和正确性。计算结果为摩天轮主轴的安全性校核评价提供了精确的数据,提高了设计效率和计算精度,其计算方法为游乐设施主轴的计算和校核提供了参考。Ferris wheel spindle is one of the important parts,which bears all the weight of the whole running structure.Whether the spindle meets the strength requirement plays a vital role in the safe operation of the ferris wheel.There are bending normal stresses and bending shear stresses on the spindle.In this paper,the bending shear stress is derived from the mechanical theory,the longitudinal section shear stress is derived using the axial static force balance of the separating body,and the bending shear stress solution formula of the spindle is obtained by the shear stress mutual equal theory.The finite element model of ferris wheel spindle was established by ANSYS Workbench and the structural finite element analysis was carried out to obtain the bending shear stress and bending normal stress of the dangerous section of the spindle.The simulation results were compared with the theoretical calculation results,indicating the reliability and correctness of the calculation results.The calculation results provide accurate data for the safety check of ferris wheel spindle and improve the design efficiency and calculation accuracy.The calculation method provides a reference for the calculation and check of amusement facilities spindle.
