Dynamic simulation of overhead contact lines and pantograph using three-dimensional MBD models

Abstract

It is important to understand the dynamic behavior of overhead contact lines and pantographs to achieve stable power supply. For this purpose, simulation of catenary/pantograph dynamic interaction is often performed. However, since lumped-mass model of a pantograph has been used in the conventional simulation, the three-dimensional dynamic behavior of the pantograph is not able to be calculated. The authors developed a new simulation method using a threedimensional model of overhead contact lines and a pantograph. This paper shows contact analysis between contact lines and a pantograph, and a simulation result when a pantograph passes a crossing section.
