Why product model information?

• As DOD acquisition contracts transition from electronic drawing based archive data sets to digital product model data, the respective agencies need to ensure that future users have access to the required data to support the lifecycle of their weapon system.

• This includes the requirements and issues involved with the:– Transition to 3-D geometry in numerous forms and quantities.– Aggregation of product models and related data from individual

components to complete weapons systems– Long-term accessibility and interpretability of the archived digital

data by future generations.

Modeling ToolShipConstructor

ShipConstructor was selected as our product modeling tool as it is relevant to NARA, NAVAIR and DLA because it is AutoCAD based. It is also relevant to NAVSEA due to the following shipbuilding projects.•Deepwater – National Security Cutter (NGSS Avondale) •LCS – both variants (Gibbs & Cox on Lockheed Martin program, Austal on General Dynamics program)•CVN – 21 deckhouse (NGSS Avondale for Newport News)•ONR E-Craft (Guido Perla for Alaska Ship & Drydock)•ONR X-Craft (Sea Fighter) – Nichols Brothers


20

Secondary Modeling ToolsTool Selection

• SoldiWorks was chosen due to current Navy Ship Design program usage

• Rhinoceros CAD: Used for Hullform, molded surfaces, compartmentation, HVAC.

• LEAPS (Leading Edge Architecture for Prototyping Systems).

35

Ongoing activities

• Developing, implementing, and testing additional STEP AP’s for use in archiving Ship Product Model Data

• Transitioning ShipConstructor model to LEAPS

• Transitioning the SolidWorks model to LEAPS

• Develop the product model repository architecture incorporating native CAD, the NAVSEA product modeling system, STEP, and ad-hoc neutral file formats using the Data Grid.

• Develop more automated methods for increasing our efficiency in populating the Data Grid.

• Develop a structural model of the engine room having enough detail to perform a stress analysis so that we can demonstrate the relationship between CAD models, FEM, analysis data, results, and documentation.
