Crew-Induced Load Measurement for Space Operations

A method has been developed to simulate and measure crew-induced and reactive loads for a variety of intravehicular and extravehicular tasks. The need for this information has expanded in parallel with the complexity of space operations, i.e. satellite servicing, on-orbit construction, use of interactive workstations, etc. The method employs the use of a dynamometer attached to an adjustable support and a 3-axis force/torque platform. Translational and rotational hand/arm forces and torques, and foot reaction forces and torques may be measured simultaneously. The apparatus has been designed for on-orbit and ground-based usage. Beyond explanation of the instrumentation, the presentation will address data on forces effected by crewmembers, and applications, implications, and integration of the information with regards to planning space operations and design of crew-interfaced items.
