Next Generation Test-Analysis Toolkit

By DE Editors

Attune 1.0 is now available from ATA Engineering, Inc. (San Diego, CA), a company which provides mechanical engineeringdesign solutions. Attune is a flexible,MATLAB-based toolkit for test-analysiscorrelation and model updating. The software began shipping to customers lastmonth.

According to ATA Engineering, Attune represents a leap forward in the area ofautomated correlationand model updating, providing a suite of powerful,easy-to-use tools for rapidly comparing test and analysis models, andautomatically optimizing analysis models to correlate closely with testdata. Users can correlate analysis models and test data based on modeshapes, modal frequencies, modal assurance criteria (MAC), or variouscombinations of these, says the company.

Attune provides complete optimizationroutines for model updating, including Monte Carlo,unconstrained quadratic minimization, and gradient-based and geneticalgorithms. In addition, multiple configurations may be optimizedsimultaneously to improve accuracy and further reduce correlation time.Attune is directly compatible with NX Nastran and MSC.Nastran,ABAQUS, I-deas NX, and MTS I-DEAS Pro Test software, and universaldata sets.

“We are very pleased to announce the release of Attune,” said KyleIndermuehle, Manager of Software Products at ATA. “This tool leveragesATA’s long history in the area of test-analysis correlation and modelupdating to provide customers with a unique, high-productivitycomputer-aided engineering toolkit. In beta testing, a key aerospacecustomer used Attune to carry out hundreds of real-time correlationiterations during modal testing of a launch vehicle payload, whereasprior to this they were limited to less than a dozen manualcorrelations a week. This type of productivity increase can greatlyreduce development costs and schedule, improve product design, anddirectly impact the bottom line for our customers.”
