摘　　要：针对狭小工作舱内,空间小,时间长,负荷轻的特点,提出了一种基于人体疲劳特性的上肢姿势评估方法。利用实验所得人体上肢肌肉疲劳特性,建立人体运动学模型。以坐标变换的方法建立了手指空间坐标求解思路,最终得到了全局坐标系中不同位置的疲劳特性值,实现人体上肢作业姿势的生理参数化定义。通过对载人潜水器内工作人员作业姿势的模拟测量,揭示算法的可行性。此姿势评估方法可以为操纵装置的工效设计以及作业空间布局提供重要参考,同时为狭小工作舱的作业姿势评估提供了可靠的评估方法。According to the characteristics of narrow working cabin that is small space,long hours and light load,we suggest a method of upper limb posture assessment based on fatigue characteristics. Using fatigue characteristics of upper limb obtained from experiments,we build the parameter sport model of human body,and establish an idea for the resolution of this type of question with the finger space coordinate transformation. The fatigue characteristic value of the different position in the global coordinate system is obtained. Finally,a physiological parameters definition of human upper limb posture is achieved. The feasibility of the algorithm is revealed by a simulation measurement of the staff posture inside the manned submersible. The upper limb posture evolution can be a reference for the control efficiency of design and work space layout. It also provides a reliable evaluation method of working postures in the narrow working cabin.
