To obtain reference data for a statistically substantiated evaluation of man's tolerance to the local pressure on the head (as applied to protective helmets kept on for a long time), 86 experiments were carried out in which 11 test subjects participated. The local pressure of 0.05-0.5 kg/cm2 was applied to 8 areas of the head. The tolerance time was(More)
Experimental data concerning the effect of head shifts on the displacement of body mass center in the man-chair system were obtained. The data helped to derive a quantitative evaluation of the relationship between body mass center displacements and head shifts. This relationship can be used to assess the displacement of body mass center in the man-chair(More)
This paper reviews the results of developing a model of craniocerebral trauma. The study led to the manufacture of a man's head model and to the development of a criterion of impact safety. The model and the criterion can be used for experimental assessment of pilot's protective helmets.
Data on the dependence of the clinical manifestations of the initial period of craniocerebral trauma in a human being on the physical parameters of the blow were treated by the method of correlation and regression analysis. A regression equation was obtained specifying linear dependence between the traumatic value of the blow and the characteristics of the(More)
An experimental study of the base deformation of isolated human scull under conditions of scull collision with an obstacle has been carried out. The findings are compared with human cerebrospinal traums phenomena. An earlier suggested continuous scull model is modified on the basis of the data obtained. It is shown that the modified model (a part of(More)
In order to determine man's tolerance, clinical symptoms of craniocerebral injuries were compared with physical characteristics of impacts. A ranking scheme of clinical manifestations of craniocerebral injuries as applied to specific flight conditions was developed. With respect to the craniocerebral injury biomechanics, clinical data were taken under(More)
