接触网简单链型悬挂目标速度适应性仿真研究

Simulation Study on Target Speed Adaptability of Catenary Simple Chain Suspension

该文为研究接触网简单链型悬挂方式下的目标速度适应性情况,选定接触线和承力索张力不变的情况下,建立不同速度等级下接触网简单链型悬挂弓网动态仿真模型,开展弓网动态仿真。结果表明,接触线张力为20 kN和承力索张力为15 kN的组合,适用于200 km/h及以下线路;当速度超过250 km/h采用简单链型悬挂时,接触线和承力索的张力需根据线路运行情况合理配置。

In order to study the target speed adaptability of the catenary simple chain suspension mode,this paper establishes the dynamic simulation model of the catenary simple chain suspension pantograph-catenary under different speed levels,and carries out the dynamic simulation of the catenary under the condition that the tension of the catenary and catenary is constant.The results show that the combination of contact wire tension of 20 kN and messenger wire tension of 15 kN is applicable to the line of 200 km/h and below;when the speed exceeds 250 km/h and simple chain suspension is adopted,the tension of contact wire and messenger wire shall be reasonably configured according to the line operation.
