In case of adding the lubricating fluid in the joint of contacting surfaces, the lubricating layer not only provides
the reduction of friction (which is transferred into the fluid), but also performs the role of an intensively damping
element, because the joint (between the contacting surfaces) is composed of 3 elements (2 surfaces and a lubricating
layer). As a barrier zone for passing the dynamic pulses, the lubricating layer diffuses the dynamic energy more
intensively than the sum of absorbing characteristics (of the decrement of oscillations) of the material of parts and
lubricant [5-7].
If we consider the process that occurs in the joint as the adiabatic compression-expansion of a lubricating layer
(described by the harmonic law Р=eiwt), then, the difference between the true value of pressure and the pressure in
the state of thermodynamic equilibrium, is equal to the ratio [2, 8]
