  • Abstract The oval-shaped which is drifted to orbiting the horizontal in the air is discussed in this dissertation. Using an additional moment drives the oval-shaped to rotate along the vertical line and observing phenomenon which the stable system transform to unstable and from unstable transform to stable. Design the oval-shaped which the major axis be a and the minor axis be b. In the air, the direction of the rotating oval-shaped is designed by three Eular’s angles, and the center of gravity of the oval-shaped is immovable. During the simulating with the different additional moment, the surface friction and the three Enler’s angles have different beginning conditions. By the different conditions, the stable and unstable oval-shaped can be simulated in the air. Through these states, the horizontal oval-shaped is transformed to vertical and the oval-shaped is still rotation. Moreover, the maximum of greatest angular velocity is produced.
