Abstract
The authors propose to use a flywheel as a stabilizer for a heavy vehicle by using gyroscopic effect. A typical flywheel is composed of a rotating disk and gimbals, which absorb the gyroscopic effect, while supporting the rotor. To produce the gyroscopic effect to stabilize the heavy vehicle, the proposed system constrains the gimbal when the roll of the truck becomes large and reach beyond the threshold value. The stability of the heavy vehicle with the proposed flywheel system and the inertia moment of flywheel necessary for stability control are examined using multibody dynamics software; ADAMS. It was found that the proposed control system is effective for prevention of roll turn over and energy storage system.
