狭小工作舱布局优化方法

针对狭小工作舱作业空间小、时间长、无舒适性的特点，提出一种基于人体疲劳特性的布局优化方法用来减轻肌肉疲劳。首先，利用实验所得人体上肢肌肉疲劳特性值，建立三维人体运动学模型。然后，以坐标变换的方法建立手指空间坐标求解思路，得到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。同时，采用专家评价法与层次分析法相结合，确定待布物的人机权重。最后，以载人潜航器舱室为例，结合蚁群算法对载人潜航器舱内主控台进行布局设计，并采用JACK软件进行模拟验证。结果表明，此布局优化方法可以缓解载人潜航器操作员的疲劳，改善载人潜航器舱室的人机环境。

Layout optimization method for narrow working cabins

According to such characteristics of narrow working cabins as small space, long working hours and lack of comfort, a method of upper limb posture assessment based on fatigue characteristics is proposed. First, using the fatigue characteristics of upper limbs from experiments, a 3D kinesiological model of the human body is built up. This establishes an idea for the resolution of this type of question with the finger space coordinate transformation method, then obtains the fatigue characteristic values of different position in the global coordinate system, and finally achieves a physiological parameter definition of human upper limb posture. The human-machine weight of objects is determined by a combination of expert decisions and an analytic hierarchy process. On this basis, in combination with Ant Colony Optimization(ACO) , the layout method for narrow working cabins is created. Finally, a simulation test using Jack software is conducted to verify that the layout method achieves more humanized design requirements.
