Abstract This work is concerned with rotors having unequal area moments of inertia which necessarily lead to equations with periodic coefficients when the bearings are asymmetric. Following a study of the main phenomena and responses to classical forces on simple models, stability and unbalance response of a large finite element model are considered using a pseudo-modal technique and Floquet theory. Results obtained are satisfactory and show that the method is effective in accurately predicting the dynamic behavior of asymmetric rotors modelled with a significant number of degrees of freedom.
