摘要
利用有限元分析软件ANSYS建立了箱形钢轨道梁的三维分析模型,并利用ANSYS中的模态分析技术对其振动特性进行了分析,获得了轨道梁的自振频率和振型,对轨道梁的工作特性有了初步的了解,为将来对轨道梁进行安全监测和状态评估提供了必要的信息和研究基础。
In this paper, a three-dimensional analytic model for steel box rail beam used for straddle-type monorail transit is established by means of finite element analysis program ANSYS. The dynamic behavior of the beam is then analyzed with modal techniques in ANSYS, and the free vibration frequencies and modes of the beam are thus obtained. The preliminary analysis results herewith may provide necessary information and research basis for monitoring the safety and evaluating the conditions of the beams in the future.
