Abstract : Theory and examples are shown for a feasible method of estimating responses of equipment to an impact of an exercise torpedo against the hull of a submarine. The equipment is modeled as a linear and elastic system whose noraml modes of vibration respond in accordance with their weight and frequency. A simple method is used for determining the effective weight of a normal mode. The method is applicable to multiple modes and independent motions of multiple supports. Keywords: Torpedo impact, Impact dynamic design, Analysis, Method.
