Double-sided dynamic balancing
Thread Content
Gentlemen: When performing double-sided dynamic balancing of a rotor, how is the remaining unbalance amount for each correction plane calculated? Thank you!
Uper = 9549*(M*G)/n. The allowable imbalance on one side is m=Uper/2r. For example, if the rotor has a mass of M=10 kg, a grade of G=2.5, a rotational speed of 2950 rpm, and a radius of r equal to 50 mm on both sides, with the distance from the support points to these planes being similar, then Uper=9549*10*2.5/2950=80.9 g.mm. The allowable imbalance per side is m=80.9/50/2=0.809 g
This is right in the middle of the support; what about a cantilever? Thank you!
