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 auxiliary power source. Uncontrolled pendulum railway vehicle cannot neutralize sensory lateral stationary acceleration in transient process. In order to prevent comfort deterioration in transient process, active control torque is necessary. Differing from conventional methods, we utilize gyroscopic moment of flywheel in hybrid powered railway vehicle. We developed a simulation model of railway vehicle considering onboard flywheel as a controllable gyroscope. Controller consists of feed-forward and energy needed for the control was calculated by numerical simulation.
