摘要
为研究刚性接触网不同跨距的弓网动态性能,建立受电弓与刚性接触网的耦合动力学模型,对刚性接触网3种跨距进行不同运行速度下的弓网接触力仿真,选取弓网接触力数据的最大值、最小值、平均值、标准偏差、0.3倍平均接触力减标准偏差作为弓网动态特性的性能指标进行比较分析。通过分析比较弓网动态特性的性能指标得出,在运行速度小于等于160 km/h的范围内,3种跨距中8 m跨距的弓网动态性能最优。
In order to study the dynamic performance of pantograph-catenary with different spans of rigid catenary,a coupling dynamic model of pantograph-rigid catenary is established,the maximum,minimum,average,standard deviation and 0.3 times of average contact force minus standard deviation of pantograph-catenary contact force data are selected as the performance indicators of pantograph-catenary dynamic characteristics for comparative analysis.By analyzing and comparing the performance indexes of the dynamic characteristics of the pantograph-catenary,it is concluded that the dynamic performance of the pantograph-catenary of 8 m span is the best among the three spans when the running speed is less than or equal to 160 km/h.
