摘　　要：建立了简单链形悬挂接触网的有限元模型和受电弓/接触网垂向耦合振动模型,计算得到其振动模态,推导了用振型叠加法计算接触网瞬态响应和动应力的方法,计算了受电弓/接触网接触压力作用下,接触网的振动响应,得到了接触网动应力随着受电弓在接触网锚段运行时间的变化情况,并与静态时进行了比较。A finite element model for analyzing a simple stitched catenary and a vertical coupling dynamical model of the pantograph/catenary system are established in this thesis. A technique of mode superposition for determining the dynamic response and the dynamic stress of the catenary is derived. The dynamic response of the catenary is analyzed under pantograph/catenary contact force. The dynamic stress of catenary is studied and in comparison with the static solution.
