Simulation of Catenary/Pantograph dynamic interaction is used for understanding the dynamic behavior of overhead contact lines (OCL) and pantographs, and stability to supply electric power to a vehicle. The authors developed a new simulation tool using a three-dimensional model of OCL and a pantograph, which can calculate their full three-dimensional dynamic behavior. Each node in the OCL model has 6 degrees of freedom; this tool can evaluate contact quality between the OCL and a pantograph system even on curved sections. Furthermore, it can evaluate the expansion/contraction of OCL due to temperature change, which affects contact quality. This paper describes this simulation tool in detail, through the example of an analysis of the contact between contact lines and a pantograph from the results of a simulation of a pantograph passing a crossing section.
