The springs, with the action of the oil-film force, are added to the turntable model. The dynamic property of the turntable is analyzed with the numerical simulation. The effect of the number of oil chambers on the frequency of the turntable is studied under two different situations, that is, a constant oil supply of the single oil chamber and the constant total oil supply. In a certain range of oil supply, under the situation of a constant oil supply of every single oil chambers, the vibration frequencies of the turntable, as the Hydrostatic Support System with different number of oil chambers, increase with the increase of the number of the oil chambers and the oil supply value, and the increase is nonlinear. Under the constant total oil supply, the effect of the number of oil chambers on low order vibration frequencies of the turntable can be ignored when the number of the oil chambers is more than six. These studies serve a basis for further studies on dynamic properties of the whole system., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=根据实际工程中的液体静压支承系统，将油膜力简化为弹簧支承，建立了工作转台的有限元模型，对工作转台的动力学特性进行了分析。通过数值模拟，研究了单个油腔供油量相同和总供油量不变两种状况下，油腔数目对液体静压支承工作转台振动频率的影响。保持各个油腔供油量相同，在一定的供油范围内，不同油腔数目的液体静压支承工作转台的振动频率随着油腔数目和单个油腔供油量的增大而增大，且这种增大是非线性的。保持总供油量不变，且油腔数目较多（大于6）时，可以不考虑油腔数目对工作转台低阶振动频率的影响。这对进一步研究液体静压支承系统整体的动力学特性提供了一定的理论依据。,
