PY - 2008 DA - 2008/04/17 TI - Performance of an Orifice Compensated Two-Lobe Hole-Entry Hybrid Journal Bearing SP - 871952 VL - 2008 AB - The work presented in this paper aims to study the performance of a two-lobe hole-entry hybrid journal bearing system compensated by orifice restrictors. The Reynolds equation governing the flow of lubricant in the clearance space between the journal and bearing together with the equation of flow through an orifice restrictor has been solved using FEM and Galerkin's method. The bearing performance characteristics results have been simulated for an orifice compensated nonrecessed two-lobe hole-entry hybrid journal bearing symmetric configuration for the various values of offset factor （ δ. ） ，restrictor设计参数 （ C ¯ S. 2 ） ，以及外部负载的值 （ W. ¯ 0. ） 。此外，还进行了具有圆形空穴入口对称混合轴承系统的双叶孔进入混合杂交轴承系统的性能的比较研究，使得设计者在选择合适的轴承配置方面具有更好的灵活性。模拟数值结果表明，对于具有偏移因子的双叶对称孔入口混合轴承系统 （ δ. ） 与圆形对称空穴入口混合杂交轴承系统相比，大于一个以上提供30至50％的直接刚度和直接阻尼系数的值。SN - 1687-5915 UR - https://doi.org/10.1155/2008/871952 do - 10.1155 / 2008/871952 jf - 司法学Pb - Hindwi Publishing Corporation KW - ER -
