摘要

The influence of a wall porosity on the pressure distribution in a curvilinear squeeze film bearing lubricated by a lubricant being a viscoplastic fluid of a Vocadlo type is considered. After general considerations on the flow of viscoplastic fluid (lubricant) in a bearing clearance and in a porous layer a modified Reynolds equation for the curvilinear squeeze film bearing with a Vocadlo lubricant is given. The solution of this equation is obtained by a method of successive approximation. As a result one obtains a formula expressing the pressure distribution. The example of squeeze film in an axial bearing (modeled by two parallel disks) is discussed in detail.
