摘要
针对目前游乐设备运行过程中,由于高周疲劳引起驱动轴疲劳失效而造成设备事故等问题,本文采用有限元分析理论并结合NCODE疲劳分析软件,对飞碟游乐设备驱动轴进行了疲劳仿真研究.首先结合设备工况对该游乐设备进行了简化和建模,然后采用ADAMS有限元分析软件进行了动力学分析,提出了多体系统拓扑构型,得到了驱动轴的载荷时间历程.利用NCODE疲劳分析软件对驱动轴进行了疲劳可靠性分析,得出该驱动轴的疲劳结果云图和各节点的疲劳寿命,并从云图中确定出驱动轴容易破坏的位置和寿命.
In the running process of amusement equipment,equipment accidents and other problems have been arising—caused by high cycle fatigue of drive shaft. In this paper,the research on the fatigue simulation of the drive shaft inside the flying saucer amusement equipment is done using the finite element analysis theory and NCODE fatigue analysis software. Firstly,the amusement equipment is simplified and modeled according to the equipment working condition. Then,the ADAMS finite element analysis software is used to analyze the dynamics. As a result,the topological configuration of the multi-body system is presented and the load time history of the drive shaft is obtained. Next,by using NCODE fatigue analysis software,fatigue reliability analysis of the drive shaft is made,the nephograms of the fatigue results of the drive shaft and the fatigue life of each node are obtained,from which the location and fatigue life of the drive shaft easily destroyed are also confirmed.
