Video: High-speed recording of the test of a crash absorber
The institute has several high-speed cameras. The usual frame rates range from 50 frames per second (fps) for quasi-static testing up to 240,000 fps in high-speed crash tests. Selected measurement signals can be recorded simultaneously by very fast transient recorders (1 GHz) and displayed synchronously.
The videos can be processed with special image processing programmes, e.g. for optical deformation analysis to obtain detailed information about deformations and displacements over time. Even three-dimensional deformations can be analysed without contact by using more than one camera.
