摘要：

The time-domain identification of modal parameters of a rotor-bearing system is helpful for condition monitoring and fault diagnosis of a rotating machine. However, it is difficult to determine the order of the system by use of the conventional time-domain methods. In this paper, a recursive STD algorithm is presented to minimize this difficulty, and experiments on a two-span rotor test rig are carried out, Test results show that this algorithm is correct and effective.
