Impact Testing is ideal for small structures, especially when boundary conditions are seriously disturbed by shaker attachment. While it requires minimum test preparation time, data harvesting is a tedious process. LMS Test.Lab provides a complete modal testing solution from measuring frequency responses to performing modal analysis using impact hammer frequency response function measurements for simultaneous response channels.
Designed for single operator use, LMS Test.Lab Impact Testing supports automatic active channel detection and calibration. During measurements, the software alerts the operator to unusual circumstances; the resulting data set is automatically discarded without operator intervention. Built-in application knowledge quickly defines acquisition parameters such as trigger parameters and FFT-window selection. Auto-accepting averages help the operator take measurements without keyboard interaction, while having a complete view on all data. Seamless integration with the analysis applications provides immediate feedback to validate data correctness.
LMS Test.Lab Impact Testing can be combined with additional LMS Test.Lab applications for faster data interpretation and analysis.
LMS Test.Lab Geometry can quickly generate wireframe and full 3D visualization of test and analysis results.
Once a geometry is made, the roving hammer excitation can be driven by the geometry nodes.
LMS Test.Lab Operational Deflection Shapes and Time Animation provides immediate feedback to validate FRF correctness by on-the-spot animation of the geometry model.
LMS Test.Lab Modal Analysis offers various fast and accurate single or multiple reference parameter estimation algorithms, and a complete set of modal model validation tools.
LMS Test.Lab Geometry, LMS Test.Lab Operational Deflection Shapes and Time Animation and LMS Test.Lab Modal Analysis are available as stand-alone analysis environments or as add-ins to LMS Test.Lab Impact Testing, which provides on-the-spot analysis.
