摘要
目的 获取我国歼击机飞行员中颈后长具有第50百分位的飞行员的颈后部三维形态数据与特征. 方法 采用自行研制的排阵探针模具装置,测量150名飞行员的颈后长,并对所测飞行员中具有第50百分位颈后长的32名飞行员进行了颈后部三维形态的数字化测量. 结果 建立了颈后部数字化测量方法.150名飞行员颈后长为81～168 mm,平均127.3 mm;颈后长符合第50百分位的32名飞行员颈后长为120～123mm,平均121.4 mm,并获得了其颈后部最小二乘法拟合曲线,构建了三维形态模型. 结论 所建立的测量方法便捷、实用、有效;所获得的结果可用于飞行员颈后部三维特征的分析,并可为火箭弹射座椅颈托部及头靠部的设计提供人机工程学依据.
Objective To obtain the 3D shape data and features of 50th percentile posterior neck length in Chinese pilots.Methods The posterior neck length was measured in 150 fighter pilots by developed probe array and then 32 fighter pilots who were in accordance with 50th percentile posterior neck length were selected based on these 3D digitized posterior neck measurements.Results The method of digitized measurement was established.The range of posterior neck length was from 81 mm to 168 mm,the mean length was 127.3 mm in 150 pilots.In 32 fighter pilots with 50th percentile posterior neck length,the length range was from 120 mm to 123 mm,the mean length was 121.4 mm.The least square fitting curve was got then and 3D model was established.Conclusions The developed equipment and method are practical and effective.The results can be applied to the 3D analysis of posterior neck shape features and to the design of the neck support and head rest of ejection seat.
