Abstract. The article is devoted to problems of hydrodynamic simulations of sliding friction in the liquid. The aim is to create an automated system for calculating the characteristics of sliding sleeves with arbitrary (smooth) profile. For this purpose developed a technique and algorithm for determining the carrying capacity of the bearing with arbitrary profile of the sliding sleeve, and developed recommendations for obtaining rational profiles of sleeve of bearing. On the basis of this methodology developed a system for calculating the characteristics of sliding bearing with the use of package of computer algebra Mathcad. Developed calculation system was used to search for variants of rational profiling of sleeve of sliding bearings. Were found variants of profile of sliding sleeves that provide an increase in carrying capacity compared with the supports that use traditional (round) profile of the sleeve.Designed system also allows quick comparison of the characteristics of sliding sleeves with different profiles.
