【摘要】：目的利用飛行仿真獲取Herbst機(jī)動中飛行員生理坐標(biāo)系下的各方向過載,并對獲得的典型數(shù)據(jù)進(jìn)行分析。方法依據(jù)典型4代機(jī)設(shè)計參數(shù),在CAD軟件中建立飛機(jī)三維幾何模型,通過飛行仿真獲取機(jī)體質(zhì)心6個關(guān)鍵運(yùn)動參數(shù),根據(jù)中國飛行員人體測量數(shù)據(jù)建立人體三維幾何模型;依據(jù)座艙和座椅在飛機(jī)中的位置建立飛機(jī)與人體裝配模型;通過人機(jī)系統(tǒng)運(yùn)動學(xué)分析獲取機(jī)動飛行時人體不同部位的各方向過載,對3 km高度、90 m/s速度下開展的Herbst機(jī)動進(jìn)行過載分析。結(jié)果人體胸部、足部和頭部各方向過載基本一致,但手部與胸部Gy曲線相差很大,手部過載峰值約為1.6 g;在人體三向過載中+Gx峰值最大,約為3.0 g。結(jié)論使用機(jī)體質(zhì)心過載曲線代替人體過載曲線會帶來較大誤差,在研究多軸向載荷對操控行為的影響時手部Gy過載曲線不能使用其他部位過載代替。
[Abstract]:Aim to obtain the overloading of pilots in the physiological coordinate system in Herbst maneuver by flight simulation and analyze the typical data. Methods according to the design parameters of typical four generation aircraft, the 3D geometric model of aircraft was established in CAD software. Six key motion parameters of body mass center were obtained by flight simulation, and the 3D geometric model of human body was established according to the anthropometric data of Chinese pilots. According to the position of cockpit and seat in aircraft, the assembly model of aircraft and human body is established, and the overload of different parts of human body in maneuvering flight is obtained by kinematics analysis of man-machine system. The overload analysis of Herbst maneuver at a speed of 90 m / s at 3 km altitude is carried out. Results the overload of human chest, foot and head was basically the same, but the curve of hand and chest Gy was very different, the peak value of hand overload was about 1.6 g, and the peak value of Gx was about 3.0 g in three directions of human body. Conclusion there is a big error in using body mass center overload curve to replace the human body overload curve. In studying the effect of multiaxial load on manipulation behavior, the hand Gy overload curve can not be replaced by other parts of the body overload curve.
