Repairing a fighter aircraft - A Look Inside

• Aircrafts are out of service for 24 to 36 months

• Very little info sharing, no structural optimization

• Every replacement part is a “custom” repair part

• Planes are rolling off the flight lines in greater number

• Limited mission configurations

(5)

Typical process and challenges

FEM generation, FEM analysis, Margin of Safety

Challenges

• FEM generation

• Retrieve data

• Integrate customer methods

• Thousands of local analyses

• Understand design changes

• Traceability for certification report

No traceability: delay on certification ü Time consuming

ü Risk of error, and on quality

No traceability on methods ü Risk of errors

ü Time consuming Done by hand

Thousands of analysis to perform Thousand of excel sheets, in- house code & tools

Done by hand Done by hand

ü Difficult to understand design change

ü No CAD/CAE associativity

50% of time spent on retrieving the right data ü 20% of time on

geometry preparation ü Design fixed very early

No easy cleaning tool

Designing monster mining trucks

Liebherr Group - Mining Trucks Optimizing a weight-efficient truck

• Optimized truck weight

• Generated multibody models significantly faster and with fewer errors than building from scratch

• Explored design alternatives that would be impractical to study with physical mockups

• Use Simcenter 3D to study behavior on various terrain

• Predict vehicle behavior with reasonable accuracy for a variety of load cases

“The only way to design a market-leading, optimally weight-efficient truck is with advanced simulation tools like Simcenter 3D for its durability and multibody

capabilities, software that we not only should use, but must use. We can’t maintain our market leadership any other way.”

James Whitfield, General Manager of Research and Development Multibody dynamics to studying the behavior

Producing high-quality and silent washing machines

“From a purely engineering standpoint, having this broad range of analytical functionality in a single suite of integrated software enables us do the best possible job of predicting noise levels early in development and helping Miele quickly arrive at an optimally quiet design.”

Miele

Enabling appliance manufacturer to reduce time-to-market

Olgierd Zaleski, Chief Executive Officer

• Compressed the time needed to develop quiet, innovative products

• Minimized sound levels by

exploring the impact of a variety of factors

• Arrived at optimally quiet design early in the development process

• Use acoustic simulation to design quietness early in the development process

• Work with Novicos to implement Simcenter Acoustics (LMS Virtual.Lab Acoustics)

Verifying that new designs meet Miele’s high-quality standards
