Study of the stability and accuracy of the eccentricity identification algorithm in fast-revolving rotor balancing problems

Abstract

Problems related to the stability of the eccentricity identification algorithm in the problem of balancing flexible rotors are considered. The accuracy of the algorithm developed for identification by static influence coefficients is studied. The physical meaning of the condition number in the eccentricity identification problem is revealed. Optimal relationships are established between the balancing accuracy, the precision of measurement instrumentation, and the dynamic model of the system under consideration.
