摘要: 周向无回油槽油腔式静压轴承能充分利用轴向和周向封油面上的动压效应,以提高轴承的承载能力。本文讨论任意油腔数的静压轴承的程序设计,利用具有较强通用性的变步长有限差分法,直接求解雷诺方程来进行轴承的分析计算。优化设计采用复合形法,以单位承载量下的功耗最小为目标函数。为使优化设计成为切实可行,采用了高低精度迭代技术、自动选择合理超松驰因子等一系列有效措施,可在IBM-PC微型计算机上运算,获得了经济机时,可供设计人员直接调用,特别适合我国国情。

Abstract: The recessed hydrostatic bearing without axial grooves is such a bearing that makes good use of the dynamic effects on the axial and circumferential lands in order to improve the load capacity of the bearing. In this paper the programming of the hydrostatic bearing with any number of recesses is discussed. For the analysis and calculation of the bearing, the Reynolds' equation is directly solved by the Finite Difference Method with inequal steps which is one of the more general numerical calculation. The Complex Method is applied in the optimum design. The total power dissipation/load capacity is regarded as an objective function. In order to make the optimum design available for use, a series of technical approaches are applied to save computer time, such as higher and/or lower accuracy iteration technique, automatic selection of the super-relaxation factors. The computer program written in FORTRAN-77 for the optimum design is worked out and can be run on the microcomputers such as IBM-PC, MC 68000 which are specially suitable to the conditions in our country.
