maximum expected sinusoidal vibration environment


maximum expected environment imposed on the space segment element and space segment equipment due to sinusoidal and narrow band random forcing functions within the launch element or space segment element during flight or from ground transportation and handling


  • NOTE In flight, sinusoidal excitations are caused by unstable combustion, by coupling of structural resonant frequencies (POGO), or by imbalances in rotating space segment equipment in the launch element or space segment element. Sinusoidal excitations occur also during ground transportation and handling due to resonant responses of tires and suspension systems of the transporters.
