operational modal analysis - Opis:
- Prediction of process stability in milling is usually based on experimental frequency response functions of machine tool and cutting force model. Alternatively, operational modal analysis may be applied for the prediction of a stability diagram. It does not require modal impact test but uses vibration signal acquired during actual cutting to identify modal parameters. Such an approach considers boundary conditions that may be different during cutting. On the other hand synthesis of frequency response function is not feasible due to the lack of scaled modal residues. Thus, in this paper modal mass obtained by means of impact test is used to calculate frequency response functions. Estimation of modal damping and natural frequency is carried out using only acceleration signals measured during flexible workpiece machining.
