In the previous lecture we introduced a dynamic balancing of rotors. Now the last time a that we can able to balance the rigid rotor using a 2 planes. In this particular case, the main aim of this particular analysis will be that somehow we can able to convert this particular reciprocating engine, whether it is single. Our Team Course Content.

Figure If the rotor is statically balanced, it will not roll under the action of gravity, regardless of the angular position of the rotor. The requirement for static balance is that the center of gravity of the system of masses be at the axis of rotation. For the center of gravity to be at the axis of rotation, the moment of inertia of masses about the x-axis and y- axis, respectively, must be zero. For dynamic balancing of rotors, Eq.

Unbalance is the most common source of vibration in machines with rotating parts. It is a very important factor to be considered in modern machine design, especially where high speed and reliability are significant considerations. Balancing of rotors prevents excessive loading of bearings and avoids fatigue failure, thus increasing the useful life of machinery. Unbalance in a rotor is the result of an uneven distribution of mass, which causes the rotor to vibrate.
