Several packages analyse a set of eigenvalues of rotor-bearing systems at given speeds. But it is still hard to identify each eigenvalue behaviours depending to speeds. We propose a solver which can continuously follow an eigenvalue modification by speed change. In our method, an eigenvalue and eigen vectors are replaced by state variables which difference are defined by the sliding mode control. Hence, the numerical integration provides variables grasping the exact value in any speed. We study on the eigenvalue analysis of the rotor supported by oil-film bearings and the critical speed calculation to demonstrate the effectiveness of our tenacious solver.
