LMS Test.Lab Spectral Testing and LMS Test.Lab Source Control provide a productive state-of-the-art modal testing solution for structural excitation by up to 16 shakers or by impact hammer. Frequency response function measurements can be performed for simultaneous channels, all supporting ICP® transducers or any voltage signal, and are IEEE-1451.4 TEDS compatible.
LMS Test.Lab Spectral Testing provides dedicated test setups for multiple shaker FRF tests. Automatic active channel detection provides one-man calibration, while the open-loop cable check and built-in digital scope troubleshoot defective cables and transducers. Specific test setup validation tools perform excitation level balance checks and input force de-correlation validation, while online reference curves help compare current measurements with previous ones or targets. A comprehensive tabular overview of measured FRFs and coherence functions overlays the selected functions automatically in the display while the corresponding measurement points can be highlighted on a geometry wireframe. Missing points and points with input overload during testing can be also automatically highlighted on a geometry wireframe.
LMS Test.Lab Spectral Testing and LMS Test.Lab Source Control can be combined with further LMS Test.Lab applications for faster data interpretation and analysis.
LMS Test.Lab Geometry provides fast wireframe generation and full 3D visualization of test and analysis results. Through TEDS support, geometry creation is further accelerated with the position information from pre-programmed TEDS transducers.
LMS Test.Lab Modal Analysis offers various accurate single or multiple reference parameter estimation algorithms, and a complete set of modal model validation tools. With the clear stabilization diagrams from the LMS Test.Lab PolyMAX parameter estimation algorithm and the automatic modal parameter selection, the analysis process is simplified and operator-dependency of the resulting modal model is eliminated.
