Abstract [en]

Currently, traffic congestion often happens in big cities every day. People demand a new conceptual vehiclewhich has a slender shape to reduce space, lightweight structure to decrease the fuel consumption andinnovative technology to adapt for multiple transportation conditions. NEWT is such a conceptual amphibious vehicle that satisfies people's requirements. However, everything has two sides. Slender shape and high centre of gravity will result in instability. When NEWT runs in low speed, it easily gets rolled over. In order to make up for its drawback, gyro-stabilizer has been applied to the vehicle. By tilting the rotational gyro, it generates a counter torque counteracting the roll motion to make the vehicle recover to an upright position.Therefore this master thesis analyses the original stability of the vehicle and the possible improvement by adding the gyro system for both land and water-conditions. The model can handle the problem that thevehicle meets periodic disturbance forces, such as wave excitation force and wind force.
