description: Theme of final qualification work: Â«Study of the pump-pocket circuit in the management of hydrostatic bearings of the heavy module LR520PMF-4Â». This work is devoted to the study of the pump-pocket control scheme with the aim of improving the characteristics of the spindle unit during the modernization of hydrostatic bearings. Tasks that were solved during the study: 1. Development of a mathematical model based on static and energy calculations. 2. Analysis of the dynamic quality of a hydrostatic bearing using methods of the theory of automatic control. 3. Development of dynamic HSB correction to ensure the necessary accuracy of the system. As a result of this work, static and energy calculations were performed, according to the results of which the following parameters were determined: the geometric dimensions of the HSB, the costs through the support of the HSB and the total power loss. Check for overheating of bearings. An analysis of the dynamic quality of hydrostatic bearings is given, a description of the dynamic model for the pumppocket control system is presented. The optimal correction option was identified in terms of the best dynamic quality.
