Vibration Control of Railway Vehicle with Parallel Cardan Drives by Traction Motor Torques

Abstract

This paper presents a method to suppress the vertical bending vibration of electric railcar by using traction motor. Dynamics of the truck with parallel cardan drives can be controlled by torque of the traction motors. This paper proposes a control method to reduce vertical vibration of truck frame by the traction motor torques to reduce car-body vibration. The motor torques are added with the traction torques of the control scheme in reverse phase for two traction motors of a truck. Experimental result shows that the control method using traction motor torque can decrease the truck frame vibration.
