WebbThe space segment equipment vibration levels are based on vibration response measurements or model prediction made at the space segment equipment attachment points during ground acoustic tests or during flight. The duration of the maximum environment is the total period during flight when the overall level is within 6 dB of the … WebbThe paper intends to present the force limited vibration notching approach as well as the lessons learned from this test. The MIRI instrument design was qualified for sine and random environments using force limited testing to limit the dynamic responses of the sensitive optical components and mechanisms while demonstrating adequate margin …
