Effect of shielding of a part of the casing of a technological explosion chamber on its stress state

Abstract:
The effect of the presence of a shield on the stress state of the casing of a real explosion chamber and the rate of decay of its vibrations was studied experimentally. Considerable decrease in the stress was observed in the shielded part of the casing and at its pole at which the shield was not installed. It was shown that the use of a local shield in the form of a shell ring significantly increased the duration of vibrations of the casing, in particular at the pole.
Keywords:
explosion chamber, strain measurement, equivalent stresses, logarithmic decrement, damping parameter.
