Research on the Vibration Characteristics of the Explosion Vessel Using Wigner-Ville Distribution

The deformation analysis of explosion vessel is very important in strength analysis and engineering design. By means of laser Doppler measurement and Wigner-Ville distribution, the expansion process of steel explosion vessels has been studied, and the frequency characteristics of the strain wave are analyzed. Finally, the experimental results of deformation and vibration frequency of vessel are given under the condition of 300g TNT explosion equivalent.
