基于虚拟仿真的民机最小机组评估初步研究

Preliminary Research on Assessment of Minimum Flight Crew Based on Virtual Simulation

本文通过对最小飞行机组条款的解读,设计了相应的模拟实验,对机组工作功能和工作量评估进行深入研究。本文采用的方法是计算机辅助分析法,基于JACK软件,利用其中的人因分析模块进行最小机组评估研究。首先在三维仿真软件中建立驾驶舱、座椅等模型,并导入JACK中。通过优化模型,并根据GJB 4856-2003中国男性飞行员人体尺寸数据,建立中国飞行员人体模型库。然后针对数字飞行员进行手部和眼部对操纵器件的可达性,不同飞行任务操作的舒适度、适配性等分析,通过实验结果验证某大型民机驾驶舱符合最小机组条款的适航要求,完成最小机组评估。

Based on the interpretation of the minimum flight crew clauses,the corresponding simulation experiments are designed to deeply study the function and workload of the flight crew.The method used in this paper is computer aided analysis,based on JACK software,using the human factor analysis module for the assessment of minimum flight crew.First use three-dimensional simulation software to establish the cockpit,seat and other models,and import into JACK.By optimizing the model to establish the human body model base of Chinese pilots according to the human body size data of Chinese male pilots(GJB 4856-2003).Then use the digital pilots to analyze hand and eye on the manipulation of the accessibility of the device,comfort,adaptability of the operation of different mission and so on.The experimental results verify that the cockpit of a large civil aircraft meets the airworthiness requirements of the minimum flight crew and complete the minimum flight crew assessment.
