Brüel & Kjær offers advanced test-to-Finite Element Analysis (FEA) tools to help aircraft and vehicle manufacturers speed up their time-to-market process.
As manufacturers face increasing demands for lighter, stronger and safer constructions; less fuel and power consumption; greater comfort and better performance, this places a big demand on their test and simulation models to accurately predict structural properties and behaviours.
Brüel & Kjær’s advanced test-FEA integration tools allow manufacturers to speed up their time-to-market process by optimising strategies for testing physical models and improving the development of FE models.
As part of Brüel & Kjær’s latest data analysis platform - PULSE 16.1 - the PULSE Reflex Modal Analysis software has been enhanced with FE interfaces for importing FE models from various leading FEA programs, such as NASTRAN® and ANSYS® - or as UFF files.
The FEA results are useful for test planning, as the modes can be animated to indicate frequency range of interest, mode density and critical modes for the modal test. These animations also help users choose optimal excitation and response locations for the modal test.
A new PULSE Reflex Correlation Analysis package for test and FE model correlation is also available. The software allows users to perform a complete visual and numerical correlation analysis of two modal models, in terms of natural frequencies and mode shapes (MAC and Orthogonality), thus validating the theoretical model.
Accurate correlation is quickly obtained by following an intuitive, yet flexible workflow process that guides the user efficiently through geometry alignment, DOF mapping, vector comparison, mode pairing and reporting.
