摘要
为验证DSA250型及DSA380型受电弓在北京大兴机场线刚性网段的受流性能,基于有限元动力学理论并采用Ansys软件对受电弓、接触网、弓网接触进行模拟仿真,计算160~220 km/h速度等级下,两种类型受电弓在刚性网段、刚性至柔性过渡网段、柔性至刚性过渡网段的弓网接触力及接触力标准差,结果显示接触力及接触力的标准差均符合标准要求,DSA250型及DSA380型受电弓均能满足北京地铁大兴机场线的弓网受流要求.
In order to verify the current receiving performance of DSA250 and DSA380 pantograph in the rigid network segment of the Beijing Daxing airport line,the simulation of the pantograph,catenary,and pantograph contact was simulated based on the theory of finite element dynamics and ANSYS,and the speed level of 160-220 km/h was calculated.The standard deviation of pantograph contact force and contact force in a rigid network segment,rigid to a flexible transition network segment,and flexible to rigid transition network segment of the two types of pantograph show that they all meet the standard requirements,so that the DSA250 and DSA380 pantograph can meet the pantograph current receiving requirements of Beijing metro Daxing airport line.
