Summary:碩士 === 國立成功大學 === 機械工程學系 === 86 === Hydrostatic bearings are most important in manufacturing of heavy machine. In general, the push powers of turbo compressor, twyer and water marine engine are loaded by hydrostatic thrust bearings. Rolling bearings and hydrostatic bearings are usually used to support the center axial and the rotation flange. Additionally, in machine tool, especial in large planing machine, hydrostatic bearings are also applied for lubrication and support. Although the hydrostatic bearing is frictionless, and can minimize the wear of frictional momentum and frictional power at lower rolling speed. However, the heavy load of bearing will cause the relative displacement of the bearing with respect to the center of support; when the displacement of the bearing becomes large, the film thickness of the bearing will be different from others. This situation can result in non-uniform load of bearings, which will yield acute damage. To avoid rising grave effect of machines, MSC/ARIES is used to analyze the normal stress of bearings, and MARC is used to analyze the contact problems of bearings.
