This paper is the first report on a series of works on stability evaluation of a multi rotor system supported by oil film bearings. Vibrational energy of each element of the system is calculated and relation between the energy behaviuor and the stability is investigated with a rotor supported by two bearings. Investigation of energy level of each bearing gives us information on an instabilizing bearing and it is known that the concept of the energy level of the bearings is very useful for design and diagnosis of the rotor system.
