A2.4 - Precise Characterization of Structure-Borne Sound Transmis-Sion Applied on Crash Sensing Technologies

Marinus Luegmair & Sebastian Wöckel
The non-destructive prospection by ultrasonic or structure-borne waves within solids is a common indirect measurement technique beside the conventional body acoustic. It is used for quality control during the production cycle or online surveillance of tools, bearings, engines and machine structures by detection of defects or location of faults like unbalanced masses. In the frame of a car safety system the structure-borne sound method is used to distinguish crash situations in civil cars. The device...
