Revised Impact Dynamic Design-Analysis Method (RIDDAM)

Abstract

Theory and examples are shown for a feasible method of estimating responses of equipment to an exercise torpedo against the hull of a submarine. The equipment is modeled as a linear and elastic system whose normal modes of vibration respond in accordance with their weight and frequency. A simple method is used for determining the effect weight of a normal model. The method is applicable to multiple models and independent motions of multiple supports. Keywords: Submarine hulls; Torpedo impact.
