Wide-band Shuttle Vibration Force Measurement


Overview
The Wide-band Shuttle Vibration Force Measurement (WSVFM) experiment is a part of the payload-to- Space Shuttle Program and is managed by the Jet Propulsion Laboratory. WSVFM is a standard secondary payload that will be integrated using the Get-Away Special (GAS) Carrier Payload Integrated Plan.

The WSVFM experiment will obtain flight measurements of the vibration forces acting between a space vehicle payload and its mounting structure and complementary acceleration data at high and low frequencies. Also, the project will provide measurements of the vibration forces generated by the shuttle engines and transmitted to the on board equipment. These measurements will enable the future evaluation of models used to derive force limits for a new, more realistic vibration test method that is used to qualify flight hardware. These measurements also will provide important vibration data for re-evaluating the dynamic environments of the Shuttle Small Payloads Project Office.

The WSVFM payload is self-supporting (the payload is battery powered and the data is recorded within the payload) and does not require crew interface. The payload will be activated automatically by the shuttle's main engine ignition vibration and will operate for about 270 seconds. After landing, the data will be retrieved from the recorders by using a personal computer.
History/Background
The primary purpose of the WSVFM and precursor SVF experiments is to validate a new, cost effective method of conducting laboratory vibration tests, which are routinely performed to qualify aerospace equipment for flight.

The WSVFM payload will be in a sealed, standard 5-cubic-foot GAS canister. The payload weighs 260 pounds --160 pounds for the canister and 100 pounds for the experiment and ballast structure.
