The critical speed and the unbalance response of rotors are calculated in consideration of a compliance which presents a dynamic characteristic of supportstructures of the rotors. The substructure synthesis method is applied on the total system modeled by the compliance matrix, which is experimentally identified at the bearing in the support structure, and the discrete mass rotor system in the method of transfer matrix. It is found that there is a possibility of calculating a false critical speed because experimental errors cause an imperfection in the compliance matrix indentified from experiments has been suggested. It is shown that this method is effective for such analyses as the critical speed and the unbalance response.
