Abstract
In the paper on the basis of Darcy equations defining a lubricant flow in porous layers and modified Reynolds equation is solved a problem of unsteady flow of viscous incompressible lubricant in the gap of a doublelayer porous damper. A case is considered when permeability in porous layers changes according to a normal low, and a combined feed of lubricant is carried out simultaneously in axial and radial directions. As a result of the solution of the problem specified there is found a field of pressures in porous layers and a lubrication layer, there are also obtained analytical dependences for efforts in an oil film, a module of unbalance transmitted force and also stationary and transitional transfer ratios are determined. It is proved that the combined lubricant feed a damper functions more stably, than at a separate axial and radial its feed. The obtained specified calculated models allowed determining the efficiency of additional factors account, and also carrying out a comparative analysis of results newly obtained and already available that defined a larger proximity of a new model to real practice.
