Abstract:

In order to evaluate the dynamic property of composite material barrel， the forced

response analysis is conducted by using mode superposition method on the basis of modal analysis and

damping analysis. The muzzle vibration status of the composite material barrel is obtained and

compared with which of the steel barrel. The results show that the response amplitude and frequency

of composite material barrel is less than the response of steel barrel. The dynamic property of the

composite material barrel is much more excellent.

Key words:  composite material barrel, forced response, finite element method
