Force Analysis of Walking at Reduced Gravity

摘要

In order to determine the primary surface reaction forces exerted by a man walking under reduced gravity, the vertical and longitudinal surface reaction forces were measured for a number of walking subjects, both on the ground and at reduced gravity levels between 0.1 and 1.0g. Experiments included the study of normal walking, tempo variation, and pressure suit effects. Both reaction forces varied almost directly with gravity. The lower walking limit observed for the unsuited subjects was .12g, where the limiting factor appeared to be the reduced magnitudes of the forces themselves rather than a change in their ratio.
