为了不断改善受电弓/柔性接触网系统的受流质量,主要采用半实物半虚拟相结合的方法,建立受电弓/柔性接触网模拟试验台,研究轨道交通柔性接触网参数对弓网接触压力的影响规律,进而研究列车弓网受流特性。研究表明:当柔性接触网的结构高度取1.5 m,柔性接触网跨距取62 m,承力索及接触线的张力取15 kN,承力索线密度取0.8 kg/m,接触线线密度取1.5 kg/m,接触线弛度取45 mm,对单个余弦波不平顺,其波长应大于3.2 m,对正弦波不平顺,其波长应大于5.5 m时受电弓/柔性接触网系统受流最佳。
In order to improve the current quality of the pantograph / flexible catenary system, a pantograph / flexible catenary simulation testbed is established by semi-physical and semi-virtual methods. The effects of the parameters of flexible catenary on rail transit Pressure impact laws, and then study the train arch flow characteristics. The results show that when the height of the flexible catenary is 1.5 m, the length of the flexible catenary is 62 m, the tension of the cords and contact lines is 15 kN, the density of the bearing cords is 0.8 kg / m, the density of the contact lines Take 1.5 kg / m, contact line sag 45 mm, for a single cosine wave is not smooth, the wavelength should be greater than 3.2 m, the sine wave is not smooth, the wavelength should be greater than 5.5 m when the pantograph / flexible catenary system by The best flow.
