Abstract
Aiming at the problem that the gun firing accuracy is influenced seriously by vibration caused by projectile injection. The wavelet transformation method was used for time frequency analysis of naval gun nonlinear finite element dynamics response. The dynamic model of the naval gun finite element was established by using the theory of nonlinear finite element, carry out the dynamic calculation, the time history of vibration signals of muzzle in firing process was obtained with the simulation system. By using the technology of the continuous wavelet transformation to analyze muzzle acceleration response, the frequency characteristic was obtained. The analysis results show that the wavelet transformation method make up the lack of traditional Fourier transform, and provide reference for the improvement and optimization of naval gun.关键词
