Balancing and Vibration - Theory of Machines
A system of rotating masses is said to be in static balance if the combined mass centre of the system lies on the axis of rotation.
STATIC VS DYNAMIC BALANCING • A system of rotating masses is said to be in static balance if the combined mass centre of the system lies on the axis of rotation. • Condition for static balancing: The net dynamic force acting on the shaft is equal to zero. In other words, the centre of the masses of the system must lie on the axis of rotation. • When several masses rotate in different planes, in addition to the out-of-balance centrifugal forces, the couple also produced. A system of rotating masses is in dynamic balance when there does not exist any resultant centrifugal forces as well as resultant couple. • Conditions for dynamic balancing: 1. The net dynamic force acting on the shaft is equal to zero. This is the condition for static balancing. 2. The net couple due to the dynamic forces acting on the shaft is equal to zero. In other words, the algebraic sum of moments about any point in the plane must be zero.1. Static Balancing
