Dynamic Automated Measurement on Light Weight Test Panels

Abstract [en]

This paper describes an automated approach to modal testing utilizing a robot control to position a Laser Doppler Vibrometer (LDV) beam. The LDV measures the velocity response of test panels to a broad band force excitation. The implementation of the laser beam approach involves moving the beam once for each member of the velocity-force set. It is critical that the beam is positioned precisely, and the measurement set is correctly correlated to the specimen geometry. A programmed robotic system was used for the laser positioning and for keeping the measurement set correctly identified with respect to the specimen geometry. The result clearly shows the possibility to automate time consuming modal measurement of lightweight structures by utilizing a robot to control a LDV.
