| Abstract: | Aiming at the damping effect of the fiber reinforced composite material barrel during gun firing, the energy dissipation formula of fiber reinforced composite material is given based on the dynamic characteristic principle of viscoelastic material. By using modal strain energy finite element analysis method, the damping analysis for some caliber composite material barrel is conducted. And the strain energy and modal loss factors are obtained for each mode of composite material barrel, which provide the damping parameters for the dynamic analysis of the barrel. |
