the invention relates to an improved method for a ground vibration test on an airplane . in the method according to the invention , the airplane is jacked up essentially undamped in conventional holding points with lifting devices . for purposes of the ground vibration test , the airplane is then excited to vibrate in a known manner using a plurality of vibration exciters , and the vibrations are acquired with a plurality of measuring transducers , in particular accelerometers . a dynamic vibration model of the airplane theoretically calculated beforehand can here be adjusted . the boundary conditions are removed during or after the ground vibration test , meaning the influence of the lifting device is “ mathematically canceled out ”, so that the determined measured values reflect the so - called “ free - free ” state of the airplane , as if the airplane had actually been in free flight during the ground vibration tests .
