Abstract

Abstract

In this paper, the strain growth of the flange bolts was observed in the experimental study of the dynamic response of the end cap and the bolts on the spherical explosive vessel. Numerical simulation based on the experiment was then carried out to detect the cause of this phenomenon. The results showed that the intensity of the pressure loading applied on the end cap and the bolts was much higher than that of the spherical vessel shell due to the strengthing effect of the opening’s structure. The resonance between the strengthened pressure loading and the periodical dynamic response of the end cap and bolts was the dominating cause for the bolt strain growth, which could be avoided by modulating the closure mass and the bolt preload.
