对一种新型的自补偿双锥面液体静压轴承进行了理论和实验研究。介绍了自补偿双锥面液体静压轴承结构与工作原理，采用小扰动法建立了其润滑油膜的理论模型，自补偿节流公式中计入了转子移动对节流间隙的影响。采用有限元方法求解了轴承的承载力、流量、刚度和阻尼系数，通过对承载力的测试验证了模型的可行性。结果表明：自补偿双锥面液体静压轴承比同条件下固定节流静压轴承的径向承载力高，且其在较小载荷下工作时具有较高刚度。

Theoretical and experimental studies were carried out on a new type of self-compensating bi-conic hydrostatic bearing.The structure and operating principle of self-compensating bi-conic hydrostatic bearing was introduced.Theoretical models of the lubrication film were built with perturbation method, and the influence of rotor motion on the restrictor gap was taken into account for the self-compensation re-stricting equation.The model was solved in finite element method (FEM)and was validated with experi-ments.Load carrying capacity,fluid flow rate,stiffness and damping coefficients were studied.The re-sults have shown that the self-compensating hydrostatic bearing has higher radial load carrying capacity than fixed-slot compensating bearing under the same condition,and it has high stiffness coefficients when used under low load.
