目前,对液体静压支承的承载特性进行计算时,一般都不考虑工作油液的压缩性和油膜压力区支承表面的“压力一弹性变形”,这对于低压支承是够精确的,而对于高压支承,其误差是较大的。本文在考虑了浊液可压缩性和支承表面“压力一弹性变形”的基础上,分析了静压支承油膜压力的分布规律和承载能力,并通过全息光弹摄影进行了试验研究,从而为高压静压支承(如柱塞泵滑履)的设计提供了新的理论依据。

At present, the bearing properties of hydrostatic support are generally not considered “compressive-elastic-deformable” of the bearing surface due to the compressibility of the working oil and the pressure area, which is accurate enough for low-pressure bearings. For high-pressure Support, the error is larger. Based on the compressibility of turbidity liquid and the “pressure-elastic deformation” of bearing surface, this paper analyzes the distribution law and bearing capacity of pressure on hydrostatic bearing oil film, and conducts experimental research by holographic photoelasticity. The design of hydrostatic bearings (such as piston pump shoes) provides a new theoretical basis.
