System for multi-shaker or hammer excitation - The entry-level LMS Test.Lab MIMO system provides a complete modal testing solution supporting single or dual shaker and impact hammer Frequency Response Function Measurements for up to 24 simultaneous channels, all supporting ICP® transducers or any Voltage signal.
The Geometry workbook allows fast generation of wireframe and full 3D visualization of test and analysis results. The Modal Shake workbook provides dedicated test setups for a dual shaker FRF test, including excitation level balance checks and input force de-correlation validation. The Modal Impact workbook offers embedded expert guidance for trigger parameter setting and FFT-window selection, with immediate feedback showing the effect of parameter changes on the last measurement. Both modal workbooks support automatic active channel detection for one-man calibration functionality. The Operational Deflection Shapes add-in gives immediate feedback to validate the correctness of FRF (transducer position, orientation, calibration, SNR, etc.) by on-the-spot animation of the geometry model.
The Modal Analysis workbook offers various fast and accurate single or multiple reference parameter estimation algorithms, and a complete set of modal model validation tools, such as MAC and FRF synthesis. With the crystal-clear stabilization diagrams from the LMS PolyMAX parameter estimation algorithm, the analysis process is significantly simplified and operator-dependency of the resulting modal model (typical for complex, highly damped structures) is eliminated.
The Modal Analysis Workbook is available as a standalone analysis environment or as add-in to the data acquisition workbooks, allowing on-the-spot analysis.
