摘要
本文用有限元法建立了简单链形接触悬挂的静动态计算模型，推导了接触悬挂初始状态的计算方法，解决了吊弦张力的计算问题，并从静态计算的角度提出了一种确定接触网初弛度的方法。用本文的方法可以对简单链形接触悬挂的初始状态、吊弦张力、接触线抬高和弹性系数以及振动特性进行准确的计算。在算例中对具体的接触网的静动态特性作了全面计算。
A finite element model for analyzing a simple stitched catenary is established in this paper,and a method for determining the innal state of the catenary is derived. By using the metnods developed in this paper,the initial state, the tensions of droppers,the elasticity coefficients and the natural frequencies and modes of the catenary can be exactly calculated.Based on the static analysis,a method for setting up initial dip of the catenary is also presented. As an illustration of the methods,the static and dynamic behavior of an overhead line system are calculated.
