运输机方向舵脚蹬人机工效设计研究

方向舵脚蹬是飞机航向控制的操纵机构，脚蹬人机工效设计的优劣，不仅影响着驾驶员下肢操纵的可达性与舒适度，同时也对飞机安全驾驶存在一定的安全隐患。运输机方向舵脚蹬设计通过对人体生理特征和人体生物力学的研究，利用经验公式，结合人体舒适坐姿二维简化模型和人体尺寸，对人体下肢操纵可达范围，脚蹬运动行程、踵点设计等进行理论分析和计算，得到运输机方向舵脚蹬的人机工效设计指标参数，并通过人机工效仿真软件进行虚拟仿真，最终得到一些合理、可用的设计参数，为运输机方向舵脚蹬人机工效设计提供理论支持和方法指导。

Transport Aircraft Rudder Pedal Design Ergonomic Research

Pedals are the operating mechanism of the plane heading control. The pros and cons of ergonomic design, not only affect the manipulation of lower limbs driver accessibility and comfort, but also has certain security hidden danger of safe driving to the aircraft. By the study of human physiological characteristics and the biological mechanics, using the empirical formula, combined with the human body comfortable sitting posture simplified 2 d model and human body size, scope of lower limbs manipulation and the pedal travelling, were were analyzed and calculated theoretically, and the aircraft rudder pedal ergonomic design parameters were got. Being virtually simulating By the simulation software for ergonomics, the reasonable and available design parameters were finally achived. The research can provide theoretical support and method guidance for the conveyor pedals ergonomic design.
