碩士 === 中原大學 === 機械工程研究所 === 106 === This project uses numerical analysis methods and experimental verification to study the dynamic characteristics of worktable supported by hydrostatic bearing. An investigation in the influence of worktable flexibility, bearing geometry, restriction parameter, design parameter of pressure compensations, and control, parameters such as viscosity and flow rate on dynamic stiffness and damping ratio will be obtained. The method in this study is to establish the oil film damping ratio scale by the harmonic excitation vibration theory, which is used for dynamic design analysis of the bearing with worktable. The analysis results provide an improvement scheme for increasing the dynamic stiffness and damping of hydrostatic bearing. This project will verify and calibrate the analysis method and results by experiment and identification.
