目的测定飞行头盔在持续性+Gz加速度作用下的位移,为飞行头盔的设计改进使用提供依据。方法通过离心机试验,获得不同+Gz作用下志愿受试者佩戴飞行头盔和装显示器飞行头盔的录像资料,对录像资料进行图像分析,获得头盔的位移曲线。结果建立了利用录像资料定量分析头盔位移的方法,获得了不同+Gz作用下头盔的位移。结论利用录像资料定量分析头盔位移的方法可行,测量结果为飞行头盔的设计改进使用提供了依据。
Objective To determine the displacement of flying helmet under the effect of continuous + Gz acceleration, which provides the basis for the improved design of flying helmet. Methods Through the centrifuge test, the video data of the volunteers wearing the flying helmet and the flying helmet mounted on the display under different + Gz were obtained, and the images of the video recording were analyzed to obtain the displacement curve of the helmet. Results The method of quantitative analysis of helmet displacement was established by using video recording materials. The displacement of helmet under different + Gz was obtained. Conclusion It is feasible to quantitatively analyze the displacement of the helmet by using the video recording materials. The measurement results provide the basis for the improved design of the flying helmet.
