Abstract

The high frequency response of a circular ring of rectangular cross section interior to a conical shell excited by a blast wave is examined. The ring supports a rigidly attached mass during excitation. It is hypothesized that the response is a function of the four excitation parameters which characterize the loading. These are: peak reflected pressure; characteristic time (pulse duration); wave engulfment time; and circumferential distribution. These parameters are varied over a range of interest in an effort to ascertain the structural sensitivity to such perturbations. A series of tests sponsored by the Department of the Army and the Martin Marietta Corporation were conducted by the Stanford Research Institute on the missile. Data acquired during these tests will be used to verify and support the hypothesis. In addition analytic correlation is presented based on parametric studies performed on a simple two degree of freedom ring model excited by a local pressure forcing function. The experimental data indicated a linear dependence of the structural response on variations in pressure, duration and engulfment. The analytic results indicated higher sensitivities by comparison, but supported the experimental results in general.
