This paper proposes a new technique to improve the current collection performance of pantographs. For this purpose, the pan springs, which are usually coil springs, are replaced with variable stiffness device. When the stiffness of the variable stiffness device is controlled in such a way that the peak frequency of the compliance characteristics is consistent with the dominant disturbance frequency from the catenary to the pantograph, the contact force fluctuation can be reduced. From the numerical simulation results, we confirm that it is possible to reduce the contact force fluctuation by using the proposed technique.
