Abstract

In order to explore the vibration characteristics of composite damping open cylindrical shell (CDOCS), the vibration differential equations of CDOCS are deduced on the basis of the principle of virtual work, combined with the folded displacement model, viscoelastic mechanics, and composite mechanics. Based on the Navier's method, the theoretical solution of vibration differential equations of CDOCS is obtained. The simulation solution of CDOCS is obtained based on ANSYS simulation model. The theoretical solution and simulation solution are in good agreement, which verifies the validity and correctness of the theoretical derivation. Based on the validation model, the changing law of vibration characteristics of sandwich composite open-ended shell is explored, and the influence of structural parameters such as length, thickness and radius on the vibration characteristics of CDOCS is analyzed.
