Mobile system for in-operation deformation analysis -
This LMS Test.Lab configuration provides a mobile solution to measure and visualize the structural deformation of any test item under operational load. The animated vibration patterns can be analyzed as time-history, or at selected frequencies for different load conditions, starting from multi-reference spectral data. Measurements are made using a portable LMS SCADAS 305 front-end, supporting 24 channels for ICP® and Voltage signals.
The Spectral Acquisition workbook offers an intuitive way to define channel parameters, acquisition parameters and multi-reference spectral processing functions. In all stages, the user gets feedback on the parameters defined, for maximum validation of the test setup before the actual testing starts. During the measurement, any processing function can be displayed and monitored on-line, including operational conditions (e.g. speed).
The time histories for all channels are directly written to the PC hard disk, in parallel to the on-line spectral processing, with a throughput performance independent of channel count, acquisition bandwidth and on-line processing. On-line processing and visualization covers a multitude of formats, including narrow-band spectra, cross-powers and octave sections.
The Geometry workbook allows fast generation of wireframe and full 3D visualization of test and analysis results. The Operational Deflection Shapes and Time Animation workbook provides easy navigation and data selection. All data types permit immediate analysis through animation of the geometry model: scrolling through the time axis like a slow motion camera or highlighting behavior at specific frequencies like a stroboscope. Any analyzed vibration pattern can be stored for future detail analysis or reporting purposes.
