Abstract: The dynamic response and vibration performance of explosive vessel in working were studied by experiment and finite element method. 3D-DIC method was firstly used to study the working frequency spectrum characteristics of explosive vessel. The deformation fields of the cover and central shell surface with different masses of explosive were acquired through 3D-DIC method. The main frequency and frequency spectrum were analyzed by FFT method. The main vibration modes corresponding to the main vibration frequencies obtained from experiments were analyzed through comparing the experiment results with finite element results.
