Gyroscope question |
| Question: |
Hey guys, I'm new to gyroscopes and don't fully understand how they work so I'm hoping someone could shed some light on some questions I have. I'm working on a project for school where my team decided to use gyroscopes to dampen/stabilize shake. The problem is that our entire team is composed of electrical and computer engineering students so this is completely out of our field of knowledge. The theory is that, when the object the gyroscope is attached to moves/shakes, the gyroscope would produce a force to resist that movement. If anyone is familiar with the Gyroglove, the concept should be same (or so we hope). What I've noticed is that most if not all gyroscopes seem to have gimbals attached to them. Is this necessary? What would happen if i anchored the gyroscope down like so? http://puu.sh/nY26v/cc6a548d7a.png. Would this still behave like a gyroscope and produce force to resist movement if I were to wave the anchor point around? Or would what I have just be like a spinning disk doing nothing? Thanks a bunch.

| | | Hey Victor,
The gimbals are not necessary, their use depends on the application. Gyros are used mainly for navigation, stabilization and for some funny experiments in teaching dynamics. Gimbals are needed if the goal is to allow the gyro to move freely relative to its base for example in the case of navigational applications. By doing so, the gyro won't interfere with the motion of its base. Check the movies to get a feeling about how gyros behave: http://gyroscopes.org/movies.asp.
For Your application You have to fix the gyro to the object to stabilize it. The gyro will have stabilizing effect only, if the movement of the base tilts the plane of rotation of the gyro. If the base move so, that the axis of spin of the gyro does not rotate, but translates only, then the gyro will be ineffective. Therefore You would need more than one gyros, if You would stabilize some general motion.
Oh yes, just one more thing. Gyros produce moments, not forces.
Regards,
Miklos
