静压轴承系统因其高阻尼能力、高刚度和运动平稳而被用于机床。最近，各个工业领域对更高刚性轴承系统的需求有所增加。为了实现轴承系统更高的刚度，应使用压缩率较低的工作流体。最近开发了具有极低压缩率的高体积模量流体。本文介绍了一种使用高体积模量流体的静压轴承系统。通过评估轴承系统的实验装置评估轴承的基本特性，然后将脱气油与常规油进行比较。此外，还评估了轴承系统的静态和动态特性，并与传统静压轴承进行了比较。实验结果证实，高体积模量流体提高了静压轴承的性能。
Hydrostatic bearing systems are used in machine tools due to the high damping capacity, the high stiffness, and the smooth motion. Demands for higher stiff bearing system have recently increased in various industrial sectors. In order to achieve higher stiffness of the bearing system, working fluid with lower compressibility should be used. High bulk modulus fluid with very low compressibility has been recently developed. This paper presents a hydrostatic bearing system using high bulk modulus fluid. The basic characteristics of the bearing are evaluated with an experimental setup for evaluating the bearing system and then compared the degassed oil with the conventional oil. Furthermore, static and dynamic characteristics of the bearing system were evaluated and compared with that of a conventional hydrostatic bearing. Experimental results confirmed that the high bulk modulus fluid enhances the performance of the hydrostatic bearing.
