航天服上躯干结构的构成主要包括各个法兰环开口及包络面,在各个法兰开口中,肩法兰是与人体交互作用的关键部位。为探究肩法兰布局的各个设计因素与人体上肢活动的相关性,采用混合水平正交试验方法设计开展试验,利用极差、方差和回归分析等手段,以人体上肢单手操作空间(RVWOH)和双手操作空间(RVWTH)作为评价指标,对航天服肩法兰的4个设计因素进行分析。结果表明肩法兰布局4个设计因素中,角度γ是影响单、双手操作空间的主要因素,以下依次是角度α,内径d和左右肩法兰中心距l;方差分析表明4个因素都对单、双手操作空间有显著或非常显著的影响;单、双手操作空间与4个设计因素关系可以用回归方程表达。通过试验研究确定了航天服肩法兰布局与人体上肢活动的相关性,为其设计及优化提供了依据。

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.
