| 摘 要： | 随着国内城市轨道交通多条线路速度等级达到120km/h,架空刚性悬挂弓网系统因共振导致受流质量下降的运行区段时有出现,因而架空刚性接触网系统跨距值的设计选用变得相当重要。结合架空刚性接触网模态分析、弓网动态接触压力频谱分析,阐述了设计时速120 km线路架空刚性悬挂接触网跨距选择为8 m的依据。

| Abstract: | Many urban rail transit lines in China have achieved the speed of 120 km/h,resulting in current quality decrease of the overhead rigid catenary system because of the sympathetic vibration.Therefore,the selection of overhead rigid catenary span becomes very important in the design.Combined with analysis of the overhead rigid catenary modal and the catenary contact force spectrum,the basis for 8m overhead rigid catenary span on the designed 120 km/h line is elaborated. |
