Rotor Dynamics Technology
Rotor Dynamics TechnologyRotor dynamics analysis began in the 1870s when efforts were made to calculate the fundamental natural frequencies of shafts. Fifty years later the effects of an unbalanced force on the response of a single rotating disk were considered. For 25 more years, until 1944, analyses were limited to simple rotors, or to graphical solutions, for the determination of fundamental frequencies. At that time, M. A. Prohl of the General Electric Company developed a general calculation method that could be applied to any rotor geometry for the determination of many frequencies. This was a key breakthrough for rotor analysis and constitutes the basis for the present-day representation of rotors.
