In the design of modern centrifugal compressors stress and vibration problems are of increasing importance. Results of research work in this field is presented about stress calculations due to centrifugal force and an evaluation of the lift forces by means of flow data. Flow measurements were discussed investigating the excitation effect to the blades. Vibration measurements telemetered from 8 blades were carried out on the compressor with vaneless and vaned diffuser. Vibration of the whole impeller is the subject of a FE-calculation.
