Vibration Analysis of Cylindrical Shell with Different Circular Angle

Abstract:

Aiming at the vibration characteristics of cylindrical shell, the different cases of cylindrical shell are analyzed through FEM, and the cases are determined according to the circular angle. The free modality results show that with the same dimension of shell, the modal shape of cases are similar to each other, the frequency increased with the increase of circular angle, but for circular angle (say 90°), the increase trend becomes lower as the frequency difference ratio is lower. In excited vibration analysis, there is a relationship between acceleration peak value and circular angle, which is illustrated by a non-dimension parameter.
