Description

The utility model relates to the field of clothing modeling, in particular to the field of creating means for protecting crews of combat vehicles from the effects of various damaging factors.

Protecting the crews of combat vehicles from the effects of various damaging factors is one of the most urgent tasks in increasing the combat effectiveness of the shock units of the Armed Forces of the Russian Federation. The protection of the crews of military vehicles, in addition to preserving the life and health of military personnel, also has an important economic aspect, since the training and education of high-level specialists to control modern military equipment requires quite large financial costs.

There are two main ways to protect crew members from shrapnel damage inside the armored vehicles: ballistic lining (lining) of the armor and the use of personal protective equipment. In this case, the most effective means is the use of individual protective kits, which are able to protect military personnel not only inside the combat vehicle, but also in the open. According to available foreign data, the use of personal protective equipment by crews of armored vehicles reduces irretrievable losses by 2-2.5 times. That is why in the armies of the developed countries of the world personal protective equipment for crew members is their mandatory item of equipment (Information sources:

Human dummies are widely used for modeling and testing protective equipment against mechanical factors. Translated from Dutch manneken "- this is a little man or from French" mannequin "- a model, a stuffed animal. Even in the Middle Ages, they began to demonstrate clothes with their help.

Known mannequin for forensic medicine. It contains a housing to which imitators of the upper, lower limbs and head are movably attached. The case is a frame of three reinforcing rods imitating the shoulder girdle, spinal column and pelvis. Each upper limb consists of two reinforcing bars proportional to the shoulder and forearm of the human body, which are connected by loops in the form of an articulation of two degrees of freedom. Reinforcing joints of the lower extremities, commensurate with the thigh and lower legs of the human body, as well as the elbow joint, are bolted with the possibility of obtaining an articulation of one degree of freedom. Bowls of thermoplastic material are attached to the areas of articular joints. Simulators of the shoulder girdle and pelvis are connected to the simulator of the spinal column using oblique jumpers. The constructive implementation of the dummy provides increased stability during forensic medical experiments (Patent for invention RU No. 2151428, IPC G09B, 2000).

Known mannequin for trying on clothes, which contains mounted on a vertical rack supporting element. The support element is made in the form of a series of diaphragms mounted parallel to the vertical column and perpendicular to it with the possibility of movement relative to the latter, and elastic corrugated shell covering them. Each diaphragm consists of at least four electromagnets, equidistant from each other in the plane of the diaphragm, mounted on brackets that are piston rods, the cylinders of which are connected to the mannequin's vertical strut and fittings through switching distributors with a pneumatic network. Ring-shaped elastic sealed chambers placed and fixed around the entire perimeter from the inside in the cavity of the rings of the elastic corrugated shell opposite the mentioned electromagnets are filled with magnetic fluid interacting with the magnetic force field of the electromagnets through the walls of the elastic sealed chambers. Electromagnets and switching switchgears are connected by a control program to a computer. The invention provides the ability to automatically adjust the dummy to various sizes and height of a person, taking into account the local features of his figure (Patent for invention RU No. 3387352 IPC А41Н 5/01 2006.01).

Known mannequin containing a frame with hinged elements, placed in an elastic shell, and on the frame are sealed containers with a system for supplying liquid filler in them (ed. St. USSR N 952250, IPC A61H 9/00).

The problem of the safety of a person inside a technical tool (in a car) arose with the birth of the automotive industry. In 1971, specialists of the American concern General Motors created an improved crash test dummy called Hybrid-1, which is still in use today. In the manufacture of the mannequin, all human proportions are taken into account, how the weight, shape and size of the head are distributed. The spine consists of elastic metal "cartilage" and bends well, the skeleton ribs are made of flexible and soft plates, and well-movable joints are used as joints. In general, the entire construction of the mannequin contains sensors and is an imitation of a single human body. Vinyl is used in the mannequin coating, which is specially selected according to the elasticity indicators of human skin. A lot of electronic sensors and potentiometers are installed on the doll, they are located in important places - the head, neck, chest, legs and arms. All this is expensive electronics, transmits information about the various loads carried by the doll at a speed of 25,000 times per second. Signals are recorded on a special memory unit, which is located behind the chest of the mannequin. The cost of a fully equipped and stuffed for testing dummy is pretty decent, about $ 250,000.

Known mannequin, which includes a bearing shell made of an elastic material such as polystyrene, having the shape of a human torso; internal sections of foam material such as foam, placed inside waterproof shells and located one above the other; elastic tubes for supplying fluid to the sections; expansion tank connected to the tubes and located in height above the upper boundary of the dummy. The principle of action of the mannequin is as follows. When testing personal protective equipment, depending on the test program, sensors for measuring the parameters of backward action at the points of the planned impact are installed on the inside of the supporting shell. The test substance is put on the mannequin and at the moment of exposure the characteristics of the backward action are recorded (Patent for invention RU No. 2074367 IPC F41H 1/00, А41Н 5/00).

The device as the closest in technical essence and the result obtained is accepted by us as a prototype.

The disadvantage of this device is the design complexity and low accuracy of data on possible damage to the internal organs of crew members of damaged vehicles.

The purpose of the utility model is to simplify the design of the dummy, reduce the cost of the device and increase the information content of research related to testing the means of protection of crews of combat vehicles from damaging factors.

The goal is achieved by the fact that a mannequin for modeling and testing the means of protection for crews of combat vehicles, made taking into account the proportions of the human body, and containing elements that simulate the muscular and musculoskeletal system, skin, and shock load sensors associated with the signal recording and decoding system moreover, in the thoracic, abdominal, pelvic cavities of the mannequin, a prefabricated monolithic cast of these cavities made from a polymeric material having a tight span 10-50 kg / m ³ , Young's modulus E = 10 ⁵ Pa, the outer surface of the impression is covered with a film of a polymer material connected with it, which changes color depending on the strength of the impact on it, and shock sensors are placed inside the impression in the localization areas of the cavity organs and large neurovascular formations. In FIG. 1 shows a general view of a mannequin.
