Abstract

The influence of the aircraft boundary conditions when setting a Ground Vibration test is always an issue. As aircrafts designs are becoming bigger is size and weight, the challenge in developing test set-ups for a successful GVT also increases. These challenges include not only the mechanical design of test devices, but also the goal to have the test performed in a shorter time, and with limited budget. Embraer decided years ago to have reliable device, which could duplicate the aircraft boundary condition, allowing at the same time fast test set-up and fast dismount. Even though, that design was modified and some opportunities had to be evaluated. This paper shows the conclusions of some variations on actual aircraft GVT set-ups, as well as studies performed in a small aircraft- like structure.
