A Computer Model for Damage Tolerance Analysis,
Abstract
In support of the Navy's effort to improve the survivability of surface ship combat systems, a computer model is being developed to analyze tolerance for combat-induced and self-inflicted damage. A damage tolerance analysis shows the effect of damage on vital auxiliary and electrical systems and relates these damage effects to the capability of the ship to continue performing its combat mission at a prescribed level. This paper discusses applications and utility of the computer model as an effective survivability analysis tool in the interactive design of ship machinery systems arrangements. The model under development will allow a user to: (1) define the geometry of a ship; (2) define the combat systems and their associated vital auxiliary and electrical generation and distribution systems; (3) simulate selective damage to the ship; and (4) assess the residual combat compability. The geometry of the ship is defined in terms of compartments, firezones, and watertight areas. Combat systems and vital electrical and auxiliary generation systems, which are identified by deactivation diagrams, are defined in terms of equipment such as radars, power panels, and pumps. Distribution systems are specified by, for example, cables interconnecting the electrical power generation equipment and the critical combat systems. Compartment locations for all combat, vital auxiliary and electrical generation and distribution systems are specified. Damage may be specified in terms of equipments and/or areas of the ship.
