Payload Vibroacoustic Test Criteria
The NASA-STD-7001A Testing Standard establishes the test factors (levels, duration, tolerances, etc.) for verification of spaceflight payload hardware used for qualification, proto-flight, and flight acceptance programs. This Standard applies to payload hardware programs including prototype, proto-flight, follow-on, spare, and re-flight.
However, this Standard does not cover test requirements for launch vehicles, payloads launched by sounding rockets, aircraft and balloons, and ground support equipment.
At Thermax, we are accredited to perform the random vibration profile, which is applicable to payload, subsystem, and component assembly levels.
Section 4.3.2 - Random Vibration Tests
Random vibration testing is required for electrical, electronic, and electromechanical components and subsystems, as well as hardware whose responses are driven by the mechanically transmitted random vibration due to vibro-acoustic environment.
Random vibration testing is performed by controlling the acceleration spectral density (ASD) over the frequency range of 20Hz to 2000Hz. The lists below describe the test types, test levels, and durations. Test profiles are tailored for their application and weight.
- Qualification Testing
- Protoflight Testing
- Acceptance Testing
- Workmanship Testing
- Qualification and Protoflight Tesing - MEFL (Maximum Expected Flight Level) plus 3dB
- Acceptance Testing - MEFL (Maximum Expected Flight Level)
- Workmanship Testing - ASD (accel. spectral density) with overall level of 6.8g(rms) (see Table 1)
- Qualification Test Duration - 2 minutes in each of the (3) orthogonal axes
- Protoflight Test Duration - 1 minute in each of the (3) orthogonal axes
- Acceptance Test Duration - 1 minute in each of the (3) orthogonal axes
