Methodology of calculation of dynamics and hydromechanical characteristics complex-loaded tribunes, greased structurally-heterogeneous and non-Newtonian fluids

摘要

Are presented development of the theory of lubrication by structurally-heterogeneous and non- Newtonian fluids complex-loaded tribounits and a design procedure of the hydromechanical characteristics necessary for the decision of problems of optimization of design data of bearings piston and rotor-type of machines. The opportunity of calculation of a field of hydrodynamical pressure in a lubricant film on the basis of algorithm of preservation of weights is stipulated under boundary conditions JFO (Jakobsson, Folberg, Olsson). The algorithm is tested on the decision of problems of calculation of bearings with an oval journal and the plug (fig.1) [1], including greased simple non-Newtonian a fluid [2]. The technique of the account of influence on hydromechanical characteristics ovality journals and plugs has allowed to prove their limiting sizes.
