摘要:
本文讨论毛细管节流和小孔节流的多油腔、无周向回油槽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。
Abstract:
In this paper the capillary and orifice-compensated multi-recess hydrostatic journal bearings without circumferential oil groove are studied. Starting with the equation of continuity of flow, through analyzing the characteristics of the bearing with any number of recesses, general formulas for calculating the pressure in each recess, load capacity or stiffness and power loss are derived, to be used in computer operations. The paper shows also the effects of some demensionless design parameters on the characteristics of bearings. With increasing shaft speed of rotation, heat evolution and temperature rise become a critical problem. Consequently, the optimum design with the aid of a computer has been resorted to, under the constraints of maxima load capacity and stiffness for a given recess geometry, with the total power loss as an objective function. In order to solve this problem, the penalty function method is applied to transform a constrained minimization problem into a seguence of unconstrained minimization problems. The optimum solution to the design problem is obtained by using Powell’s method. Both the flow chart and the computer program in FORTRAN are worked out in detail.
