Tridimensional Study by Scanning the Variability Anthropometric Head Human Use of Ballistic Helmets

In the development of new products and improvements adequacy of the artifacts have been a concern for ergonomics, with a focus on the preservation of physical, mental and social integrity of the human being. The high competitiveness and the search for new technologies that distinguish industrial products indicate conducive to the use of new technology as an innovation factor environment. In the military arena, it is known that on the battlefield many soldiers did not consistently use the ballistic helmet due to his discomfort. Currently studies report that approximately half of the deaths in the battle fields is due to projectiles triggered in the soldier's head. However, other studies show that this artifact after a few minutes in continuous use, it becomes heavy and unstable for some users. In other words, it was proved that some soldiers do not wear a helmet when necessary is because even bothers. It is at this point that is the purpose of this paper. Through Scanner Tridimensional with computational analysis tools such as CAD, is seeking to capture images and data of the human head to a previously defined group of people. It is intended to verify the measures are consistent with ballistic helmets currently used in the military and also examine whether there are differences of these measures. With the process of Tridimensional Scanning are obtained with precision details of surfaces that traditional methods Caliper and anthropometric tape, which is not observed because their analysis is one-dimensional. Thus the technique proposed in this paper is presented as a tool capable of providing a differential for the design of ballistic helmets, creating new possibilities in their sizing.
