A spatial coupling model to study dynamic performance of pantograph-catenary with vehicle-track excitation

In the high-speed railway industry, pantograph-catenary system is responsible to provide continuous electric energy for train. The suffers multiple impacts from complex work environment. vehicle-track excitation one of normal disturbances interaction. Previous studies only consider vertical effect vibration on To address this deficiency, both and models are constructed in paper. validations verified by experimental test world benchmark, respectively. pantograph base follows translations rotations car-body caused random rail irregularities. combination with a spatial contact model between wire strip, carbody can be fully considered statistical analysis, stochastic analysis frequency performed make sense track irregularities deviation point away strip centre also analysed. results show that reliability shows decrease degradation quality. may cause de-wirement extreme conditions. Finally, an application example given evaluate dynamic performance running China network realistic
