Dynamics of a Gyroscope

Application ID: 15007

Gyroscopes are used for measuring the orientation or maintaining the stability of airplanes, spacecraft, and submarines vehicles in general. They are also used as sensors in inertial guidance systems.

This model demonstrates the modeling of a mechanical gyroscope. It analyzes the response of the spinning disc to an external torque coming on the disc due to the rotation of the frame. It is shown that the disc is able to maintain it’s orientation when it is spinning with a high speed. This fact can be explained with the principle of conservation of angular momentum.

In the second part of the model, the motion of a spinning top is analyzed. The external torque induced precession and nutation motion of the spinning top is computed.
