LMS Operational Deflection Shape Analysis is used to visualize the deflection shapes of a structure while it is in operation. Vast amounts of run-up or stationary data are brought to life by animating the geometry immediately after the run, to visualize an ‘action replay’ of what is really happening. The LMS Test.Lab solutions support automatic scrolling along the time axis, for a slow motion camera effect, or along frequency, order or speed axes, for a stroboscope-like analysis. Seconds after acquiring the signals, the user can verify if all transducers were working correctly, observe what deformation patterns relate to the noise issues at a given speed, and benefit from an overall better understanding of the structure’s vibration behavior.
LMS Operational Deflection Shape Analysis solutions provide insights into the main vibration and acoustic problems, both during the test as during the post-processing analysis of the structure while it is in operation. By looking at the animation of spectra, frequency cuts, order cuts and throughput time data, immediately after the measurement and through online monitoring of the key results during the throughput acquisition progress, engineers enjoy increased data confidence and avoid re-testing. In this way, test results have the desired quality level, allowing better-informed decision-making for test based engineering and troubleshooting of a structure under operational loads.
