Cost estimation capacity of the drive rotor

The analysis of the beat vibrations of the drill string is carried out. We considered the reasons of beat occurrence. According to the results of experiments, we established the extreme range of critical values of axial load, which determines the availability of the beats. We identified dependencies and recommendations on drilling parameters.
