![]() ![]() When you watched the Space Shuttle or SpaceX launch, you would here the annunciation for max-Q, this is the altitude and speed when aerodynamic loads are the greatest. ![]() An aircraft experiences random vibration from aerodynamic turbulence on the fuselage and wings and both random and sine vibration from the engines.ĭuring the ascent, a rocket experiences significant random vibration from aerodynamic loads and from the rocket engine. Which, is vibration comprised on many different frequencies at different amplitudes.įor example, an automobile traveling on the open street or highway, will have vibration input from the tires rolling on the road surfaces irregularities. Most vibration experienced in life is random vibration. For example, vibration testing of aircraft components and structures has resulted in a high level of commercial aircraft safety. The thing being vibration tested is typically referred to as, the Unit Under Test (UUT) or Test Article.Ī vibration testing is a vital step and time tested methods to both prove a product will survive the rigors of its intended use and improve product quality. Vibration testing is the process of simulating or mimicking real-life conditions a device, product, component, or a structure will or could experience during its lifetime. ![]()
