BALLISTIC TORSO SIMULATOR FOR DETERMINING THE PROTECTIVE PROPERTIES OF THE ARMOR VEST

摘要

The utility model relates to devices for testing personal protective equipment, in particular, to ballistic test benches for assessing the protective properties of body armor against the effects of high-speed damaging elements (PE), secondary (low-speed) fragments (fragments) and an air shock wave (HVW) of an ammunition explosion. The purpose of the utility model is to create the design of a ballistic torso simulator (BIT) for assessing human life and safety when using torso protection equipment (armor vest), and it is of practical interest to determine the parameters of the formation of an acronym contusion injury when the bulletproof vest is not broken (conditionally damaged) by various high-speed damaging elements, impact of secondary (low-speed) fragments (fragments) and the impact of an air shock wave of an ammunition explosion to assess the possible consequences of the damage (injury) ). To achieve this goal, a torso simulator, made in accordance with the anthropometric parameters of a person, contains the internal cavity, divided by an elastic septum into the chest section and the abdominal section, filled with fluid. Additionally, the internal cavity of the thoracic section contains a bubble - a simulator of the lung (left and right), filled with air and granules of solid material with the addition of a foaming agent. Inside each section and / or on the elastic partition are universal blocks containing a three-axis accelerometer and a piezoelectric intracavitary pressure sensor. The torso simulator is installed either on mini-sleds moving in the direction of impact of PE, falling cargo and air defense, or on a spring-type shock absorber to move the torso in space. The useful model provides a unified quantitative assessment of the parameters of the formation of the damage to the object of protection when the bulletproof vest is not pierced by various high-speed damaging elements, impacts of secondary fragments and exposure to an air shock wave of an ammunition explosion.
