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].
