Run Data Averaging & Comparison Organizer LR.jpg

LMS Test.Lab Run Data Averaging & Comparison Organizer

The worksheet provides a comprehensive view of all available 2D data (order sections, frequency sections, octave spectra or octave sections) and is designed to compare and average results from various tests very quickly for validation and/or processing. Selected data are immediately displayed via powerful display filling modes in user-defined screen layouts. Embedded navigation supports fast scrolling across functions or measurement points. Individual measurements are included or excluded from automatic average and envelope calculations by tick-box selection. Averages and envelopes can be stored in a project database.

Signature Throughput Processing LR.jpg

LMS Test.Lab Signature Throughput Processing

The LMS Test.Lab Signature Throughput Processing host worksheet offers a convenient display overview of time histories, including zoom-in, immediately after completing a measurement using the parallel throughput functionality, without leaving the data acquisition application. The “Processing Data Set” definition functionality organizes and combines recordings for batch processing. A “Quick Spectral Map” provides insight into spectral contents to guide the appropriate processing parameter selection. The software offers efficient processing of multiple throughput files with a common set of processing parameters. Tracking channels can be used to control the time data selection to be processed. It supports trial processing on a limited number of channels and includes batch processing with auto-saving of results. The module also offers a preview of processing results with auto-switching of the display.

Principal Component Analysis LR.jpg

LMS Test.Lab Principal Component Analysis

LMS Test.Lab Principal Component Analysis helps reduce complex noise and vibration problems to more manageable, independent, uncorrelated problems with multiple partially correlated references. These problems range from structure-borne road-noise to the combined effects of air-conditioning compressor and engine noise. By applying singular value decomposition techniques on a multi-reference crosspower matrix, this matrix is decomposed into its principal components, yielding as many single reference sets of crosspowers as there are references. The solution also features other functions such as virtual coherence and virtual spectra. Principle component analysis results can be used for further transfer path analysis.


PolyMAX LR.jpg

LMS Test.Lab PolyMAX

LMS Test.Lab PolyMAX is available as an add-in to LMS Test.Lab Modal Analysis and LMS Test.Lab Operational Modal Analysis. It is an advanced modal parameter estimation technique that offers superior identification of modal parameters. Its main advantage consists in damped structure identification, where more modes can be identified into a higher frequency range. LMS Test.Lab PolyMAX also detects less well-excited modes. Thanks to the clear stabilization diagram, mode selection can be performed in larger frequency bands and with higher confidence. With LMS Test.Lab PolyMAX, an advanced modal parameter estimation technique has been introduced that renders the final modal model user-independent. It is capable of extracting more modal information out of the same data-set as conventional parameter estimation techniques.


Automatic Modal Parameter Selection LR.jpg

LMS Test.Lab Automatic Modal Parameter Selection (AMPS)

LMS Test.Lab Automatic Modal Parameter Selection (AMPS) is an add-in tool for LMS Test.Lab Modal Analysis and LMS Test.Lab Operational Modal Analysis. The tool automatically selects physical poles in the stabilization diagram. It was developed based on the knowledge and skills of experts who assess stabilization diagrams. Benchmark research positioned it as a guidance tool for novices as well as an advisory tool to speed up the pole selection process for experts in both standard and operational modal parameter estimation cases.

Geometry LR.jpg

LMS Test.Lab Geometry

LMS Test.Lab Geometry provides fast wireframe generation and full 3D visualization of test and analysis results. Point coordinates are defined in Excel-like tables, while connections and surfaces are graphically defined in the display. The geometry can be copy/pasted from Microsoft Excel or imported from a UFF file, STL file, LMS CADA-X, FEA model or LMS Virtual.Lab. Through TEDS support, geometry creation is further accelerated with the position information from pre-programmed transducers.


Photogrammetric Geometry Definition LR.jpg

LMS Test.Lab Photogrammetric Geometry Definition

This option within LMS Test.Lab Geometry consists of software to process digital pictures, made with a digital camera from different viewpoints around the test object. The software automatically identifies target points on the pictures and reconstructs the 3D geometry model of the object without any operator interaction.

Geometry Scanning LR.jpg

LMS Test.Lab Geometry Scanning

This option within LMS Test.Lab Geometry consists of hardware and software to digitize point coordinates of a test structure. Digitization is done through a hand-held probe with a built-in camera that uses image recognition of reference panels to determine its position in 3D. The calculated coordinates are immediately available in LMS Test.Lab Geometry and the LMS Test.Lab display. It supports measurements of a global axis system as well as Euler angles (transducer orientation). It works extremely well on small and large structures with irregular geometry or high point density.
