Analysis of Static Characteristics and Optimization of Basic Parameters of Static Pressure Gas Bearings for Precision Machine Tools

Abstract

This paper conducts research on the hydrostatic gas bearings of precision machine tools, deeply analyzes their static characteristics and optimizes the basic parameters. Firstly, through theoretical modeling, the static characteristic equation of the hydrostatic gas bearing was derived, covering key indicators such as stiffness and bearing capacity. Subsequently, combined with the numerical simulation method, the static characteristic performance of the bearing under different working conditions was simulated to verify the accuracy of the theoretical model. The research finds that the static characteristics of gas bearings are significantly affected by parameters such as gas supply pressure and bearing clearance. Based on this, the basic parameters of the bearing were optimized and designed by using the optimization algorithm, and the optimal parameter combination was determined, which significantly improved the load-bearing capacity and stiffness of the bearing while reducing power consumption. The experimental results show that the application of the optimized hydrostatic gas bearing in precision machine tools can significantly improve the processing accuracy and stability, providing a theoretical basis and technical support for the design of high-performance bearings in high-end precision machine tools, and has important engineering application value.
