摘要
在正常满载工况和极限偏载工况条件下,利用虚拟仿真技术对典型旋转类游乐设施-大摆锤驱动头进行了动力学仿真分析研究,考虑了转盘旋转对驱动头回转支承的影响,更加真实的获取了大摆锤驱动头部分的运动学和动力学特性。在此基础上进行了驱动轴疲劳强度计算,为大摆锤的结构优化设计提供了理论基础。
To obtain the more detailed dynamic characteristics of large pendulum in complex working condition and analyze its failure mode, this paper puts forward the dynamic simulation of a full-toad and part-load large pendulum considering the influence on the slewing bearing because of the rotation of gondola. Therefore, the submitted simulation obtains the more authentic kinematic and dynamic characteristics of large pendulum driving unit. Thereafter, the fatigue safety calculation of drive shaft has been done, which provides the base for optimizing the design of large pendulum.
