Abstract:

The methods for theoretical analysis and for experimental analysis, separately used, are insufficiently to study the behavior under vibrations of the shafts of the mixing devices, because the computation in the fields of this kind of shafts, doesn`t only partially take into account the real static of loading.The paper shows some numerical values for the coefficient k, which introduces the effect of the axial force on the computation of the own real rotational speed, in the case of the propeller impellers and standard open type turbine impellers.

Keywords:

correction coefficients, real own frequency, theoretical own frequency.
