【Abstract】 In this article,transverse free vibration of annular elastic membrane is studied. On the basis of a mathematical model of the vibration,its formal solution as well as the eigenfrequencies and nodal lines is obtained,which is useful in the field of transverse vibration of annular elastic membrane.Also the results may be applied to some musical instruments.更多还原
