Research on Hand Operation for Cockpit Layout Optimization

以优化飞机驾驶舱布局设计为目的,对人体的手部操作进行了研究。首先,对驾驶舱显控装置的关联性进行分析;其次,以减小人体的手部操作路线总长为目的,对驾驶舱人机界面进行了布局优化分析;接着,以人手部几何模型和人手部Kane动力学模型为依据,建立了基于人手部操作舒适性的驾驶舱布局优化模型;最后,通过实际案例对人机界面上的操作路线进行了仿真分析;利用CATIA仿真人在驾驶舱中的手部操作姿态,计算出人手的操作舒适性,并通过舒适性评价模块进行了结果验证。理论分析和仿真结果表明,在飞机驾驶舱中相对重要的设备应布置在手部操作舒适性较高的区域,并且在布局设计过程要尽量缩短人体手部操作设备的路线,该模型提高了驾驶人员的操作效率,可作为驾驶舱布局优化设计的参考依据。

To optimize the layout design of aircraft cockpit,research on operating of hand was conducted. Firstly,correlation between display device and control device in the cockpit was analyzed. Secondly,for the purpose of reducing length of hand operating route,layout optimization of cockpit man-machine interface was analyzed. Then,the mode of layout optimization based on hand operating comfort was established on the basis of geometry model of human hand and hand Kane dynamic model. Finally,simulation of hand operating route on man-machine interface was analyzed through practical case. Human hand operating gesture in the cockpit was simulated in the CATIA and joint angle data was obtained; Result was validated through CATIA module of comfort evaluation. The theoretical analysis and simulation results show that relatively important equipment should be arranged at the area that hand operation comfort is high,and length of hand operating route should be shorten as far as possible in the process of layout design. The model can improve the operating efficiency of driver and provide reference of cockpit layout design.
