Optimization Centre What is it?

How is it Structured?


Provides Focus and Momentum to Strategically execute Weight Reduction Efforts within Concept and Development Phases

A Skill Centre of Excellence with a Focus on Weight Reduction / Performance Balance [ ]

Weight must be managed Actively! The Optimization Centre provides the Environment!

Creates a natural Home and Culture for Development of Optimization Processes and Best Practice

Relieves the Weight Pressure off the Function Attributes Teams


Process People

Technology Intelligent Software Tools Integrated into the

Process and Facilitating People

Creativity

Re-configured to Accommodate

The Technology and the Increased People

Interaction

Integrated Multidisciplinary

Project Team Facilitated by the

Process, Empowered by the Technology

Stress Integration

• Altair HyperWorks for IFEM loads model build

• On-site support from experienced HyperWorks users

• Back office support to resolve local issues

• Strict IFEM requirements

• Assembly model build

• IFEM integration

• IFEM Generation – CAD to delivery 6 weeks

IFEM GENERATION


Stress Integration

LOADS

• Prepares supplied pressures to IFEM-

mappable pressure fields

• Two-step process 1. Create pressure fields

2. Map pressure fields to element sets

• GUI mode for creating pressure fields

• Visualisation of pressure fields

• Loads – Supply to IFEM 2 days


Stress Integration

RESULTS EXTRACTION & SUMMARY

• Results Extraction & Summary Tool (REST)

• Automated extraction of enveloped

loads/deflections from .op2 files

• Automated population of summary Excel

templates

• GUI/Batch modes

• Results extraction & summary – weeks

(previously months)


Stress Integration

STRESS ANALYSIS

• Traditional methods used for sizing via MS Excel

• In parallel, same FE models optimised using OptiStruct sizing optimisation

Hinge Beam

SUPPLIERS

• Supplier data (loads/deflections) provided on demand (via REST)

• Eg, seal deflection requirements, latch loads

• Local seal expansion (radial, tangential and longitudinal)
