description: Theme of final qualification work: âStudy of hydrostatic bearings of the spindle of the LR400PMF-4 module while improving its technical characteristicsâ. This work is devoted to the study of the characteristics of the LR400PMF-4 module when replacing the original hydrostatic bearings with new ones during modernization. In the course of the work, the following tasks were performed: 1. In this work, static and energy calculations are performed. 2. The analysis of the dynamic quality of a hydrostatic bearing using methods of the theory of automatic control 3. Logarithmic amplitude-frequency, phase-frequency characteristics and transients for the automatic control system are constructed 4. The optimal correction option has been identified from the point of view of the best dynamic quality in both fine and draft modes of operation. 5. An option is proposed for using standard metal bellows as part of a corrective circuit. For the best option, its main characteristics are determined. As a result, the geometric dimensions of the hydrostatic bearings, the costs through the support and the total power loss were determined, an overheat check was performed. A hydraulic corrector and a spindle unit of the machine were also designed. The dynamic characteristics of hydrostatic bearings were analyzed for various variants of the LR400PMF-4 module in versions with and without correction.
