摘　　要：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 helmet displacement under sustained -＋Gz environment so as to provide basis for improving design of the helmet prototype with its mounted system. Methods By means of motion video analysis technology, the displacement curves were obtained from video data of subjects, wearing helmet with/without mounted display devices during ＋ Gz tests in human centrifuge. Results The method for determining the helmet displacement was established. A serial helmet displacements under various ＋ Gz with/without mounted devices were obtained. Conclusion The method of determining the helmet displacement with video motion analysis is feasible. The displacement data can be used for evaluation of the helmet designing.
