Stability and Vibration of a Rotating Circular Plate ...

This paper predicts transverse vibration and stability of a rotating circular plate subjected to stationary, in-plane, concentrated edge loads. First of all, the equation of motion is discretized in a plate-based coordinate system resulting in a set of coupled Hill's equations. Through use of the method of multiple scales, stability of the rotating plate is predicted in …

It does so in the case of a production grinder as at Al, where grinding wheel and workpiece turn in the same direction, forward to the operator as in ...


Modeling a Helicopter Swashplate Mechanism | COMSOL …

A swashplate is a device that is used to transmit the pilot's commands from the non-rotating fuselage to the rotating rotor hub and blades. The fact that the rotor blades are rotating at a very high speed makes the swashplate mechanism's task more challenging. The mechanism consists of two main parts: a stationary and a rotating swashplate.
