Dynamic Design Analysis Method
Dynamic Design Analysis Method (DDAM) is a shock hardening program that estimates the dynamic response of a component to shock loading caused by the sudden movement of
a vessel, which may result from depth charges, mines, missiles and torpedoes. DDAM is used
primarily to validate designs for U.S. Navy use. Derived from response
spectrum stress analysis, which is used primarily to study responses to earthquake loading, DDAM simulates the interaction between the shock-loaded component and its fixed structure. The free motion of a vessel in water will produce a higher shock spectrum than a heavy structure would on ground. DDAM takes this effect into account in relation to the weight of the equipment,
mounting location and orientation of the equipment on the vessel.
