The development of modern technology makes increasingly stringent requirements for materials, and improving the reliability and durability is an urgent task for many industries. One of the most important elements of the automatic coupling device of the car is the absorbing device. The parts included in it must meet high standards, be reliable and provide the necessary hardness and mechanical properties of the materials throughout the life cycle of the car. One of these parts included in the friction unit of the absorbing device is a movable plate. In the present work, an example of modernization of the absorbing apparatus through the use of modern methods of modeling and manufacturing of a fixed plate is given. The technical result is to reduce consumption of materials of the movable plate, and to simplify the manufacturing process of the plate by making it from rolled steel.

Justification and results of pilot studies of influence of parameters of a matrix of fixing of the special soft polymeric edges forming the additional locally concentrated rigidity of external material of the warmed clothes of a special purpose is presented in article. Technical characteristics and standard restrictions for the textile material considered at the heart of the projected product taking into account the requirement of GOST and operational criteria are given. Data on modern ways of increase in resistance of an external cover of clothes to the deforming influences for the purpose of preservation of internal volume and, as a result, necessary thermal insulation of clothes are submitted. On the basis of established experimentally dependences of rigidity of the modified material on width and thickness of polymeric channels the way identification of extreme density of filling of polymers of the internal surface of integumentary material with it taking into account the requirement of hygienic and operational character is offered.

Providing the claimed performance characteristics of the absorber throughout its life is the most important task that ensures the correct operation of the coupler. Increasing requirements for increasing the speed of movement and the volume of freight traffic make it urgent to increase the reliability of the absorbing apparatus by improving the design of its components and components (housing, friction plates, wedge, etc.).

The analytical assessment of change of office properties of heavy-duty details of friction pairs of the cart of the freight car on the first depot repair is presented. The technique of definition of iznos of details of the cart is applied to determination of faults. The most subject are shown to defects nodes of the cart of the freight car.
