The initial analysis and discussion are made on the several applied technological problems in the static balance test and acceptance for the rolled steel integral wheels of rolling stock, such as the relations between the wheel running speed and the permissible unbalance and the eccentric distance, the relation between the eccentric distance and the radial pulsating of the wheel hub bore, the effect of the shape and position tolerances of wheel processing on the balance quality, and the determination of the permissible unbalance tolerance.
Based on the mordern dynamic balance technique, using a homemade "drying cylinder dynamic balance test bed", Nan-ping Paper Mill calibrated dynamic balance of the drying cylinders of a China-made 3150mm paper machine and meanwhile ameliorated the manufacture technology of the rolls successfully, thus the higher speed machine's demands for dynamic balance quality could be met.
In this thesis ,the author research the balancing theory of rigid rotor, and introduce the influence coefficient balancing. Then the procedure of balancing of wind turbine is introduced.
Further studies are necessary to clarify the best way to balance quality of life (by preserving organ function) with growth control of potentially malignant tumors in the pancreas.

For the multi-stage pump and single-and double-stage pumps of max.continuous speed over 3800r/min,double-flat dynamic balance should be carried out for the rotor of them at low speed according to API610.If the pump rotor as a module is balanced,the unbalance residual test should be carried out.Passing through several tests,if the components are corrected according to the high-quality and grade,the module can attain the requirements of lower grade,i.e.the module need not be corrected for the component being ...
