本文在考滤油液本身和所含气体可压缩的条件下,分析了在阶跃载荷作用下液体静压支承的过渡过程,求得支承系统过渡过程的特性方程、过渡过程延续时间、支承间隙的位移量,以及各参数对过渡过程的影响。在上述理论分析的基础上,得出改善静压支承过渡特性的措施,为提高机床主轴支承和运动精度,提供了新的理论依据和途径。 This paper analyzes the transition process of hydrostatic pressure bearing under the action of step load under the compressible conditions of the oil and the gas contained in the test fluid, obtains the characteristic equation of the transition process of the bearing system, the duration of the transition process, the bearing clearance The amount of displacement, as well as the impact of various parameters on the transition process. Based on the above theoretical analysis, the measures to improve the transition characteristics of hydrostatic bearing are obtained, which provide a new theoretical basis and ways to improve the bearing and movement accuracy of the machine tool spindle.
