Abstract:

The upper torso architecture is the fundamental component of the spacesuit, which consists of flange apertures and envelope surface. Among the flange structures of the scye bearings, namely shoulder apertures, is the key section in the interaction between spacesuit and human body. In order to study the correlation between the scye bearing configuration and the mobility of upper limbs, the mixed-level orthogonal experiment is conducted. And these four influential factors are analyzed with the experiment by means of range, variance and regression analysis. During the analysis, relative volume of workspace with one hand(RVWOH) and relative volume of workspace with two hands(RVWTH) are selected as evaluation criteria. It is shown that among the four design factors, angle γ is the most important one for both RVWOH and RVWTH, followed by angle α, diameter of the ring d and distance between scye bearing centers l in turn. All the four factors have significant influence on RVWOH and RVWTH, as the variance analysis shows. The correlation between RVWOH, as well as RVWTH, and those factors could be described by regression expression. The correlation between spacesuit scye bearing and mobility of upper limbs is achieved through the experimental research, which could provide some reference for the design and optimization of the scye bearing configuration.

Key words: spacesuit, scye bearing, mobility of upper limbs, correlation, orthogonal experiment
