摘　　要：大直径无轴式摩天轮工作原理是电动机通过减速机减速,带动驱动轮,使其低速转动。使用ANSYS14.0有限元软件建立摩天轮数值模型,采用理论与数值模拟相结合的方法分析了大直径无轴式摩天轮的结构强度的安全性。通过对摩天轮的悬臂架、支撑环、轨道及吊箱轴在运行状态和大风状态下的强度分析,研究超大直径无轴式摩天轮结构。研究结果表明,超大直径摩天轮的悬臂架、支撑环、轨道及吊箱轴在运行状态和大风状态下的屈服强度、安全系数及最大应力能够满足相关规范要求。摩天轮的主要结构构件具有较高的安全性,其中悬臂架在运行状态下最大应力73.4 MPa,安全系数为5.2;在大风状态最大应力196 MPa,安全系数为1.8,满足结构设计规范的要求。研究结果可为大直径无轴式摩天轮的结构设计与施工提供理论与实践参考。The working principle of the large diameter no-shaft ferris wheel is the motor through reducer reducer,drives the driving wheel, make its slow rotation. Using finite element software to establish the no-shaft ferris wheel ANSYS14.0 numerical model, adopt the method of combination of theory and numerical simulation analysis of the large diameter no-shaft type safety of the structure strength of the no-shaft ferris wheel. Through to the no-shaft ferris wheel cantilever rack, support ring, orbit and box axis in the running state and the strength of the strong wind condition analysis, research on large diameter no-shaft wheel structure. The research results show that the large diameter cantilever rack, support ring of the no-shaft ferris wheel, track and box axis in the condition of the running state and winds of yield strength and safety coefficient and maximum stress enough to meet the requirements of the relevant specification. Main structures of the no-shaft ferris wheel has high security, the cantilever rack maximum stress under the running condition of 73.4 MPa, safety coefficient is 5.2;maximum stress state in the wind 196 MPa,safety coefficient is 1.8, meet the requirements of structural specifications. The results for the large diameter no-shaft ferris wheel structure theory and the practice reference for the design and construction.
