In this paper, the theory of the part 1 for the two-bearing rotor system is extended to a multi bearing rotor system by using the transfer matrix method. The extended theory is applied to the three-bearing rotor system and it is experimentalily proved. Specially the effect of bearing pressure on the stability of the rotor system is experimented for the above rotor system and compared with the theoretical result. Finally it is concluded from the above discussions that the proposed theory is useful for diagnosing the unstable rotor system and for improving the bearings.
