基于仿真方法研究中间接头对弓网接触压力的影响

Study of the Impact of the Inter Locking Joint on the Contact Pressure of Pantograph-catenary System Based on Simulation Method

中间接头是刚性接触网的重要部件,其状态直接影响着弓网受流质量。本文建立了包含中间接头的刚性接触网有限元模型,利用该模型对弓网接触压力进行了仿真,通过与广州地铁三号线弓网接触压力实测数据进行对比,验证了模型的有效性。在此基础上,对中间接头注入故障,通过仿真方法研究中间接头失效对弓网接触压力的影响。

The inter locking joint whose status has a direct impact on the current-collecting quality of pantograph-catenary system is an important part of rigid catenary.A rigid catenary finite element model including inter locking joint was established to simulate the contact pressure of pantograph-catenary system.The validity of the model was verified by comparing the simulation results with the measured data of Guangzhou Metro Line 3.On this basis,the failure of the inter locking joint was injected into the model to study the influence of the inter locking joint failure on the contact pressure of the pantograph-catenary through the simulation method.
