With GOM’s optical 3D Aramis system, material properties and behaviour throughout the design and manufacturing workflow can be thoroughly understood. This capability contributes to improved product quality, and reduced costs and time for R&D departments in the automotive, aerospace, civil engineering, consumer goods and biomechanics industries. GOM Correlate software is used for the inspection and evaluation of 2D or 3D data that is derived from the Aramis sensor or other metrology systems. GOM Correlate Professional software offers all features of GOM Correlate, plus additional user benefits to increase the efficiency of workflow, among other things.

One application-specific feature is vibration analysis in the automotive and aerospace industries. For example, the fan blades of modern turbines for the aerospace industry have to be continuously checked, inspected and, if necessary, maintained to withstand extreme operating conditions during their lifespan. GOM’s Aramis 3D testing system supplements GOM’s ATOS system, which measures the surface defects of fan blades. Aramis can be used to record 3D displacements during a hammer impact test. Then, the software shows the displacements of all points measured with different frequency responses in a full-field or point-based manner in all three spatial directions. Based on this data, the operating deflection shapes (ODS) can be calculated to compare them with the simulation mode shapes.

Another newly devised feature in GOM Correlate Professional enables contour detection and the analysis of airbag deployment tests in the automotive sector. This software tool tracks the contour of the airbag in a high-speed video recording, and helps to identify the maximum deflection point in the local co-ordinate system of the steering wheel.

A further added feature of crack tip detection facilitates the tracing and evaluation of crack point trajectories. The feature can be used for a range of applications in the research of materials, such as metals, plastics and composites.

Last but not least, the measured data from typical material tests, such as Nakajima, bulge, tensile, bending, shear and hole expansion, is evaluated in the software to determine characteristics. This data is used as input parameters for numerical simulations, enabling a more precise material model and a more accurate prediction of material behaviour. Also, the measured 3D data can be combined with imported temperature data from an infrared camera in the GOM Correlate Professional software, so that the correlation of the thermal and mechanical component behaviour can be obtained and analysed.
