Balancing Method of Multi-span, Multi-bearings Rotor System : 2nd Report, Balancing for a Flexible Rotor Considering Constraint of the Correction Mass

抄録

We investigated a method of balancing a flexible rotating shaft, in which the magnitude of correction masses is constrained. Analytically, we used the least squares method, but we introduced a constraint coefficient into the performance function. The magnitude of correction masses is controlled by the constraint. Experimentally, we applied the above method to one rotor of a 5-span, 10-bearing rotor system and obtained good balancing results.
