  1. Integrating Design and Analysis Into a PDM Environment Keith Hunten, P.E. Lockheed Martin Aeronautics

  2. Overview • Enterprise Design and Analysis Information Integration with ISO 10303-209 • Critical and Detailed AP209 - Based PDM Concepts • An AP209 Integrated Iterative Design - Analysis Cycle • Conclusions

  3. PDM CAD CAE AP209 Enterprise Design and Analysis Information Integration with ISO 10303-209 • Enables sharing of PDM controlled composite and metallic design, analysis, material properties/specs information • Enables automated, electronic feedback of product shape, performance, and property analyses to CAD with respect to PDM product structure and versioning • Platform to extend engineering analysis STEP coverage into other analysis disciplines such as Fluid Dynamics • Provides a long term, potentially growing, repository crucial to many industries and vendors • Neutral format for PDM/CAD/CAE

  4. Next Higher Assembly / Version Part / Version Part / Version Design Documents Nominal Design Shape File Standard PDM Design Information Management • Indentured list of assemblies and components • Configuration and revision management • Associated data management • Design shape model(s) • Other related design information

  5. Critical AP209-Based PDM Concepts Allow Analysis to Revise Independently of Related Design Next Higher Assembly / Version Separate, Versioned Analysis Part / Version Analysis Design Version Relationship Analysis / Version Part / Version Analysis Documents Design Documents Three Classes of Shape Nominal Design Shape File Idealized Analysis Shape File Analysis Shape and Report File(s)

  7. An AP209 Integrated Iterative Design - Analysis Cycle • Key features include: • The management of nominal and idealized shapes • Multiple idealized shapes • Multiple analyses • Electronic feedback of analysis modifications and recommendations to design

  9. AP209 Enables Analysis Feedback to Design • The original Part1 and it’s nominal design shape (NDS1) for a point of reference (node to hook into PDM) • Part1_Version2, the final Analysis_Version2 (FEM3) and the idealized analysis shape that reflects the performance requirement changes (IAS3) • The analysis report containing the rationale documenting the design changes (modes/frequencies, stiffener buckling, model idealization and tuning process) Part1_Version1 Analysis2 Analysis_Design_ Version_Relationship1 Analysis2_Version2 Part1 NDS1 Cross-Section Shape Representation FEM3 Analysis Report Representation Part1_Version2 IAS3

  10. Integration of Design and Analysis Information in a PDM is a Powerful Systems Integration Approach • ISO 10303-209 provides a standardized meta-model for the implementation of PDM Design - Analysis data management • PDM Customization straight-forward • Automation of a PDM - managed Design - Analysis cycle furthers the goal of truly integrated systems • AP209 provides a standardized capability to share information between Design and Analysis disciplines
