The model of vertical acceleration impact on backbone of member of the crew

This paper presents procedure methodology allowing to evaluate the impact of vertical acceleration (mine detonation under the vehicle) for damages of backbone of the crew member This problem is presented globally with stress on model being the estimator of the backbone damages. Then this study includes standard requirements in this field and discusses the necessary instrumentation and then method for development of model input data is indicated. the vertical impact model is presented on example. The mechanisms allowing to evaluate the level of potential injuries are presented in the final part in this paper. The range of problems concerning metrology of physical values associating explosion and evaluation of its impact on the human body is very wide. Problems discussed in this paper do not exhaust this field. The research are under way on several topics for their more full recognition. Development of this field will be correctly used, having in mind the aspect and usefulness of such research. The main criterion for evaluation of explosion impact on people protected by armour of the vehicle is the measurement of physical and mechanical values occurring during explosion. The high accelerations and pressures constitute serious danger for health and life of people. Tests are necessary to determine effectiveness of the crew's protection both in vehicles and in other objects.
