Reduction of vibration in the cabin can be achieved by increasing the area of vibration absorption by placing on the ceiling and floor vibro-absorbing facings. The process of absorption of vibration occurs due to the transition of the energy of oscillating particles to heat due to frictional losses in the pores of the material; therefore, for effective vibration absorption, the material must have a porous structure, the pores must be open from the side of the vibration and join together (unclosed pores) so as not to prevent the penetration of the vibration wave into the thickness of the material. As a vibration-absorbing cladding, we use a construction in the form of a layer of a homogeneous porous material of a certain thickness, reinforced directly on the surface of the fence.

The analysis of safety clutches shows that, despite the high rates of scientific and technical progress in the field of mechanical engineering, the development of safety clutch designs is noticeably lagging behind, and their technical and operational characteristics in general do not fully comply with modern requirements for the protection of machine drives. Friction clutches have a high response accuracy, but at present they do not provide the necessary level of protection against overloads. For a certain period of time, these performance characteristics met the necessary requirements for accuracy of operation. However, due to the steady increase in the technical characteristics of machines and mechanisms at present, some technological equipment requires the implementation of technological processes to preserve existing power factors with minimal (up to 7 … 10%) deviation of the nominal values. Such equipment may include, for example, forging and stamping equipment. To ensure a high degree of constancy of the working forces and moments in the drives of the specified equipment, the use of safety couplings with a significantly higher accuracy of operation within the above limits is required.

From studies aimed at summarizing the results of private surveys, conditions of high accuracy SFC with single-loop negative feedback are obtained. These conditions reflect the dependences of the magnitude of the coefficient of force and the spacer force generated by the feedback control device on the current coefficient of the gain value of the coefficient of friction, which theoretically ensure the limiting value of the torque transmitted by the clutch, which leads to failure-free operation of the crank presses.

Studies of safety couplings have shown that when the friction forces in splined joints of friction disks and half couplings are taken into account, the moment of friction of the clutch increases compared to the moment calculated without taking these forces into account. Among the safety clutches, friction clutches occupy a special place in use in crank presses due to the increased accuracy of limiting the transmitted load. This allows you to increase the efficiency of protection of parts and drive units of machines, as well as reduce their weight and dimensions. Friction disks are pressed against each other with the force created by the spring, and the moment of friction arising between them ensures the connection of the leading parts with the followers. The friction force in the slots significantly reduces the transmitted force of pressing on subsequent disks, but its influence is not taken into account in existing studies.
