【Abstract】 A mechanical model to simulate the shrink fited shaft section is developed. The model pays attention to describe the mechanical behaviour of the shrink fit when the shaft is deflected. The transfer matrix across the shrink fit section is established. In order to examine the validity of the model, both the computational and experimental work have been done. The natural frequencies predicted by the model are found to be in agreement with the observed values. This shows the effectiveness of the present model.更多还原
