|
摘要
为保证车辆运营的安全性及稳定性,针对国内某型动车组转向架用抗侧滚扭杆装置的刚度、强度及疲劳特性进行研究。分析其在车辆运行中的受力状态及承载情况,基于有限元软件ABAQUS建立了抗侧滚扭杆装置的力学模型,对其刚度、静强度进行分析,并在静强度分析的应力值的基础上,通过Fe-safe软件进行了疲劳性能分析;同时,对抗侧滚扭杆装置进行了刚度、静强度、疲劳性能试验验证。基于有限元分析与试验测试得出:扭杆轴及扭臂所选取的材料满足安全性要求;计算刚度与试验结果相差3.1%,静强度与试验结果偏差在5%以内,为车辆抗侧滚扭杆装置的设计提供了参考。
In order to ensure the safety and stability of vehicle operation, the stiffness, strength and fatigue characteristics of the anti-rolling bar device used in a certain type of EMU bogies in China are studied. The stress state and loading condition of the vehicle in the vehicle operation are analyzed. Based on the finite element software ABAQUS, the mechanical model of the anti-rolling bar device is established. The stiffness and static strength are analyzed. On the basis of the stress value of the static strength analysis, the fatigue performance analysis is carried out through the Fe-safe software. At the same time, the anti-rolling bar device is tested for stiffness, static strength and fatigue performance. Based on the finite element analysis and test data, it is found that the material selected by the torsion bar shaft and the torsion arm can meet the safety requirements; the stiffness calculated by the finite element method is 3.1%, the error of the static strength calculation and the test result is within 5%, which provides reference for the design of the vehicle anti rolling bar device.
