摘要:
本文探讨了一种新型滑动轴承——小孔式(毛细管式或孔口式)周向不均匀分布的动静压滑动轴承,它综合利用了静压轴承和动压轴承的优点,制造简单,比油腔式静压轴承和隙缝式动静压轴承的性能优越,是一种很有前途的轴承型式。随着机器向高速、大功率方向发展,功率损耗是个突出矛盾。本文编制了在满足等式和不等式约束条件下,以单位承载量下的功率损耗为目标函数进行优化设计的通用FORTRAN优化设计程序,以提供最佳设计数据。本文还对油膜的破裂和再形成,空穴区雷诺方程式的边界条件,进油小孔处的流量连续性方程式以及这种轴承的程序设计和通用优化设计程序进行了较详细的讨论。
Abstract:
In this paper a new type of hybrid journal bearing—hole entry (capillary or orifice)hybrid bearing with non-uniform distribution of holes in circumference is studied. It has advantages of both hydrostatic and hydrodynamic bearings and it is easy in manufacture. The results show that its characteristics are be tter than those of recess hydrostatic bearing or slot entry hybrid bearing, so that it seems to be a kind of journal bearing with a good development. With increasing the speed and power in machine, the energy comsumption becomes a critical problem. In this paper the exterior penalty function techni que and Powell’s algorithm are applied and the general computer program written in FORTRAN for the optimum design is worked out in detail with the (total power dissipaion/load capaclty)as an objective function, subject to equality and inequality constraints, so that the optimum parameters for this kind of bearing ean be presented. Besides, the rapture and reformation of oil film, the boundary conditions in Reynolds’ equation in cavitation region, the equation of continuity of flow rate in hole entry region, the computer program for this kind of bearing and the general optimization program are discussed in much more detail.
