Abstract: The effect of stiffness of shock-absorbing pads of a real explosion chamber on the degree of vibration damping and maximum stresses in the body of the camera is experimentally and numerically investigated. The results are analyzed. A relation between the seismic effect on the foundation after a charge explosion inside the chamber and durability of its operation is revealed.

Keywords: explosion chamber, pulse loading, numerical calculation, shock-absorbing pad, strain measurement, vibration damping parameter.
