| Abstract: | 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. |
