Wheel shimmy of an aircraft landing gear is one of self-induced vibration. Wheels and tires equipped at the bottom of a landing gear will have yaw oscillation about the vertical axis when shimmy occurs. Such shimmy was observed at the nose landing gear on a small jet aircraft. Investigation succeeded to replicate the shimmy at the laboratory component test, which determined some specific conditions where shimmy would occur. The shimmy problem was finally resolved by the following improvement - The steering collar was modified to have a viscous resistance feature for more damping and a more stable friction feature.
