Abstract
Through the year’s preventive maintenance, which is based on vibration measurements has grown in importance to reduce costs. However in industry nowadays there is still a great need for good analytical prediction models that describe the dynamics of rotating structures. In this paper it is first shown how to build a model for for undamped gyroscopic systems. Secondly the model is analysed and used to make a parametric study for the design a test rig. It is found that the third and the fourth eigenfrequency changein function of the rotation speed due to the gyroscopic effect. Finally the experimental modal testing of rotating structures is discussed. The methods to excite a rotating structure in order to obtain the modal parameters are studied.
