Unformatted text preview: EXPERIMENTAL METHODS in ENGINEERING Balancing Report What Causes unbalance ? Unbalance in rotating mechinery has become an increasingly important problem in the development of high speed rotating mechinery where relaibilty is a significiant consideration. Unbalance is the most common source of vibration in the rotating components of mechines. For example in turbo mechinery, drive shaft, machine tool elements... By definition balancing is the process of attampting to improve the mass istribution of a rotor so that it rotates its bearing without uncompansated centrifugal forces. In this experiment, first we observed the unbalance rotational system in two planes. After that we have tried to eliminate the unbalance of the system by adding certain masses in the planes one by one. By doing this we aimed to correspond the axis of the rotating system with the rotation axis. In the elimination of the unbalance we tried to calculate the vectoral changes that rotation axis....
