We have created the rotating machinery library to carry out analytical investigations for diagnosis by transfer matrix method in Modelica. In this paper, rubbing components for partial rub are implemented in our rotating machinery library. In this research, the model in which the rotor come into contact from a non-contact state by a pulsating external force is analyzed. The relationship between the contact configurations and the generation of various kinds of vibration is investigated. We validated the rubbing model in one side contact case with a rotor kit. By simulation, we reproduced the time history, the orbit and the full spectrum characteristics of the rotating shaft measured by the experiment precisely.
