Onboard Equipment

Shipboard equipment needs to satisfy stringent maritime and naval requirements for durability, shock resistance, and functionality. Traditional DDAM (Dynamic Design Analysis Method) analysis is a manual procedure in which results from frequency response analysis are postprocessed to provide an estimate of shock resistance. DDAM is a required simulation document generated during design of shipboard equipment and mounting systems. Inefficient procedures for DDAM analysis are one hurdle facing the Shipbuilding industry today.

Part of the Abaqus Unified FEA product suite from SIMULIA, DDAM for Abaqus is an add-on to Abaqus/Standard that can be requested by the customer. It provides an efficient means to perform DDAM simulation through an interactive user interface and generate the associated reports as specialized output data and tables-a key to improved productivity. For routine analyses, DDAM for Abaqus can also be executed in "batch" mode allowing a user to easily conduct multiple DDAM analyses on different models within a design environment.
