A FEW REMARKS ON CONTACT LOSS IN PANTOGRAPH-RIGID CATENARY SYSTEM : EFFECT OF LATERAL VIBRATION OF COLLECTOR

In a current railway system, there is a problem that pantographs are sometimes detached from catenary. The faster the train becomes, the more problematic it would be. We investigate experimentally and discuss the problem using the simple model, of which the motion takes place in a mechanical similar manner with the real pantograph.
