A complete mathematical model for a multi-bearing rotor system incorporating a newly developed active journal bearing has been presented. Both a non-linear model and a general linearization method have been developed. The system configuration parameters (the relative positions of the bearings) were

A consideration is provided of the possibility of identifying changes in the residual unbalance of a multi-bearing rotor system. It is assumed that the relative motion of the rotor journals with respect to the bearings can be measured before and after the change in unbalance take place. Furthermore,

A general approach has been developed for on-site identification of the actual configuration (alignment) of multi-bearing rotor systems (e.g., a turbogenerator unit). The identifcation procedure is based on the monitored trajectories of the relative motion of the journals with respect to the bearing

Static indetermination is a common problem in the dynamic analysis of most multibearing rotor systems. This paper presents a systematic treatment of this problem. It is taken into account at the stage when the general mathematical model is constructed for a complete multi-bearing rotor system. The p

The rotor-to-stator rub is one of the main serious malfunctions that often occur in rotating machinery. Previous research has provided enough tools to judge the existence of this fault. However, it is still a di$cult task to detect the rubbing position in a multi-disk rotor system. In this paper, th
