本文讨论毛细管节流和小孔节流的多油腔、无周向回油楷的液体静压向心滑动轴承,从流量连续性方程出发,对任意油腔数的轴承特性进行分析,导出油腔压力、承载量和刚度、流量以及功率损耗的通用计算公式,以便上机运算;说明了一些无因次设计参数对轴承特性的影响。由于轴的转速越来越高,轴承的发热和温升是个突出矛盾。为此,对给定的油腔几何尺寸,讨论在承载能力和刚度为最大的约束条件下,以功率损耗为目标函数,利用电子计算机进行最优化设计,用罚函数法将有约束最优化问题化为一系列无约束最优化问题,采用 Powell 法寻求最优解,编制了详细的程序框图和 FORTRAN程序。
This article discusses the capillary throttling and orifice throttle multi-oil chamber, no circumferential back to the oil-free radial hydrostatic radial plain bearings, starting from the flow continuity equation, the number of any oil chamber characteristics of the bearing analysis, the export of oil Cavity pressure, load capacity and stiffness, flow and power loss of the general formula for the computer operation; illustrates some of the dimensionless design parameters of the bearing characteristics. As the shaft speed is higher and higher, the bearing heat and temperature rise is a prominent contradiction. Therefore, for a given oil cavity geometry, under the constraint condition that the bearing capacity and stiffness are the maximum, the power loss is taken as the objective function and the electronic computer is used to optimize the design. The penalty function method is used to solve the constrained optimization problem Into a series of unconstrained optimization problems, using Powell method to find the optimal solution, compiled a detailed program diagram and FORTRAN program.
