| Abstract: | In this paper,the stator core and the end cover of disc machine are equivalent to annular plates,and then the analytic expression used to calculate natural frequency of the machine stator system is obtained depending on some modification of the natural frequency formula of annular plate transverse vibration.Moreover,natural frequency of a prototype machine stator system is evaluated using this expression and the calculating results are compared with the experiment results,which are basically coincident with... |
