文摘

A single-arm pantograph of metro train was studied in this work. The mathematical model of a single-arm pantograph was first established and an optimal design method to obtain the geometric parameters of the pantograph was proposed. The 3D model for the pantograph was then built and the simulation was performed by using virtual prototyping technology to ensure superior performance of the optimized pantograph. The fatigue test of pantograph-insulator system was performed under two operating conditions: Electric pantograph lifting and real train operation. Fatigue test results validated the stability of the optimized pantograph system.
