Test-FEA integration

Integrating testing and Finite Element Analysis (FEA) helps to cut development costs, reduces the number of physical prototypes, and shortens the time from concept to production.

Using baseline Finite Element (FE) models, you can optimize your structural tests early in a project and then improve the Finite Element models using the enhanced test results.

BK Connect® offers powerful tools to gain better confidence in the test and simulation results and to improve essential engineering judgement skills, benefitting test engineers, analysts and management.

Test FEA integration

BK Connect offers one platform for test planning (pre-test analysis), structural measurements and analysis and FE model correlation.

FE models can be imported from leading FEA programs such as Nastran® (MSC, NX, NEi), ANSYS® and ABAQUS® into BK Connect Modal Analysis for performing test planning by investigating the simulation results in terms of frequency range of interest, mode density, mode order, critical modes, etc.

The simulation results can, furthermore, be used to optimize the number and locations of excitation and response DOFs, and an accurate test geometry decimated from the FE model is easily created. Once the modal test has been done, the results can be compared with the simulation results for validation.

BK Connect Correlation Analysis lets you go a step further by performing a complete visual and numerical correlation analysis to identify shortcomings in the modal tests and any areas of insufficient modelling quality in the FE models. It is a strong tool for designing optimal test conditions and evaluating different modelling strategies.
