摘要
介绍一种用于轨道巡检作业车辆的结构特征,并详细介绍其采用的导向系统,这是保证车辆在轨道上安全行驶的重要部件。然后建立整车动力学模型,并利用多体动力学软件(ADAMS)对其进行动力学分析,由安装在滑动基座内部的可伸缩弹簧的弹簧力变化得出巡检车在通过曲线轨道时导向系统的动态极限载荷。最后利用有限元软件(ANSYS)对连接导向轮系和车身的关键部件——导向架进行应力强度分析。结果表明,导向系统的强度设计满足要求。
The structure of a track inspection vehicle was introduced, and the guide system was highlighted, which was important for safety of the vehicle driving on track. Based on vehicle model built before, then, dynamics analysis by mtdtibody software （ADAMS） was developed. Dynamic loads of the guide system were obtained from the force of the spring laid in the guide slide block. I,astly, the strength analysis of the guide frame, which is key part to link guide tire sets and vehicle body, is carried out by finite element method software （ANSYS）. The results of analysis verified that the strength designed for guide system is satisfied.
