Abstract

Flywheel was considered as long life and high energy density auxiliary power source in hybrid traction system of railway vehicles. However, it is necessary to evaluate the gyro-dynamic interaction between current vehicle and additional flywheel. This paper proposes a new method on tilting control of railway vehicles using gyroscopic moment obtained from onboard flywheel primarily used as the auxiliary power source. In order to prevent comfort deterioration in transient process of pendulum railway vehicle, active tilting control torque is demanded. The authors developed a simulation model and conducted an examination of railway vehicle considering onboard flywheel as a controllable gyroscope.
