Vibration Recordings on the Shuttle Treadmill Using an Accelerometer (DTO 652)

Scientific Name: Homo sapiens Species: Human

The Shuttle Treadmill has been the primary exercise device flown on recent missions. The concern regarding treadmill exercise and its vibration impact on the shuttle mission objectives has necessitated the use of accelerometers to quantify the frequency and magnitude of the vibration during treadmill exercise. This information assisted in designing an isolation device for the treadmill, allowing for the evaluation of alternative exercise devices in terms of the vibration generated, and allowing quantification of the vibration affecting science research. The Space Acceleration Measurement System (SAMS) hardware was used for measuring the levels of vibration.

The purpose of this study was 1) to identify the magnitude and frequency of the vibration generated by the treadmill (during DSO 476 exercise) at the source and on the middeck locker. This determined whether the vibration was amplified or attenuated by the middeck structure and 2) to identify the magnitude and frequency of the vibration generated by other sources of vibration (VRCS, OMS, PRCS, nominal crew activity, and quiescent activity) at the middeck locker. This information was obtained from the SAMS data.
