Analysis of the Current Collection Quality of the Variable Speed Zone of the Pantograph-Catenary System

There are many variable speed zone during train operation. Meanwhile, the curved zone also is an important zone when the train passing by and the train will slow down. However, rarely research on quality of the current collection in variable speed zone. This paper based on Multi-body dynamics and Optimal Energy saving theory, establishing a rigid catenary model and Multi-rigid body of pantograph, studying the influence of the acceleration on the variable speed zones and the optimal quality of current collection as the target function, seeking a set of optimal accelerations.
