Abstract
FIELD: weapons and ammunition.
SUBSTANCE: invention relates to tests of personal protective equipment of a person, namely to assessment methods of protective properties of armour helmets against action of high-speed striking elements - small arms bullets and fragments formed during explosions of HE ammunition. Besides, the proposed technical solution can be related to special medical equipment. An assessment method of protective properties of armour helmets by determining risk of under-armour contusion head injury consists in action with striking elements of fire arms on an armour helmet put on a dummy head made according to anthropometric parameters of a human head and recording of consequences of action by measurement of dummy deformations. The method differs from the known ones by the fact that there measured is a value of elastic deformation of the dummy base in a direction perpendicular to the base plane, quantitative assessment of risk of under-armour contusion head injury is performed as per risk index Kr according to a chart of Kr dependence on maximum elastic deformation S of the dummy base, and the found quantitative value Kr is used as a parameter characterising protective properties of the armour helmet; with that, at value Kr of less than 0.50 an allowable risk degree is forecasted, and when Kr is equal to and more than 0.50, a high risk degree of occurrence of under-armour contusion head injury is forecasted, with that, material with elasticity modulus of 0.2 to 0.5 GPa is used as material for the dummy head base.
EFFECT: method allows characterising damage to health in a certain and quantitative manner, which is related to occurrence of under-armour contusion injury at penetration of a bullet or a fragment into the armour helmet.

Description
Изобретение относится к области испытаний средств индивидуальной защиты человека, в частности к способам оценки защитных свойств бронешлемов от воздействия высокоскоростных поражающих элементов - пуль стрелкового оружия и осколков, образующихся при взрывах осколочно-фугасных боеприпасов. Также предлагаемое техническое решение может быть отнесено к области специальной медицинской техники. Способ оценки защитных свойств бронешлемов путем определения риска заброневой контузионной травмы головы, заключается в воздействии поражающими элементами огнестрельного оружия на бронешлем, надетый на имитатор головы, выполненный в соответствии с антропометрическими параметрами головы человека, и регистрации последствий воздействия посредством измерения возникающих деформаций имитатора. Способ отличается от известных тем, что измеряют величину упругой деформации основания имитатора в направлении, перпендикулярном плоскости основания, количественно оценивают риск нанесения заброневой контузионной травмы головы по индексу риска Кр по графику зависимости Кр от максимальной упругой деформации S основания имитатора, а найденное количественное значение Кр используют в качестве показателя, характеризующего защитные свойства бронешлема, причем при величине Кр менее 0,50 прогнозируют допустимую степень риска, а при Кр равном и более 0,50 прогнозируют высокую степень риска возникновения заброневой контузионной черепно-мозговой травмы, при этом в качестве материала для основания имитатора головы используют материал с модулем упругости от 0,2 до 0,5 ГПа. Предложенный способ позволяет конкретно и количественным образом характеризовать ущерб здоровью, связанный с возникновением заброневой контузионной травмы при попадании пули или осколка в бронешлем.The invention relates to the field of testing personal protective equipment, in particular, to methods for assessing the protective properties of armored helmets from the effects of high-speed damaging elements - bullets of small arms and fragments generated during explosions of high-explosive fragmentation munitions. Also, the proposed technical solution can be attributed to the field of special medical equipment. A method for assessing the protective properties of bulletproof helmets by determining the risk of contusion injury to the head, is to use a bulletproof helmet mounted on a head simulator, performed in accordance with the anthropometric parameters of the human head, and register the effects of exposure by measuring the resulting deformations of the simulator. The method differs from the known ones in that they measure the amount of elastic deformation of the simulator base in the direction perpendicular to the base plane, quantify the risk of applying an acronym contusion head injury by the risk index K p according to the graph of K p versus the maximum elastic deformation S of the simulator base, and the quantitative value found K p is used as an index characterizing the protective properties Armed helms, wherein when the value K p less than 0.50 predict acceptable degree of risk, and for K equal to p greater than 0.50 ohms and predict a high risk of occurrence of contusion zabronevoy traumatic brain injury, wherein as the material for the base material using a simulator head with a modulus of 0.2 to 0.5 GPa. The proposed method allows you to specifically and quantitatively characterize the damage to health associated with the occurrence of acronym contusion injury in case of a bullet or a fragment in the armor.
