浅析高教研究期刊的现状和未来

1997年，国家对期刊进行了大的整顿。取消了所有内部刊号的期刊，而将其转为内部资料。也就是说，原来这一部分拥有“内部刊号”的期刊，从此就不再是期刊了。在高等院校，受到影响最大的莫过于高教研究类期刊了。

倾斜轴颈轴向运动对粗糙表面径向滑动轴承润滑性能的影响研究

通常对轴-径向滑动轴承进行润滑分析时,均忽略多种因素综合作用下轴颈沿轴承轴线方向的运动状况,与轴-轴承系统中轴承的实际工作状况存在较大差异。以轴-轴承系统为研究对象,综合考虑轴颈轴向运动、表面形貌和轴颈倾斜,基于平均Reynolds方程,建立了耦合轴颈轴向运动的粗糙表面径向滑动轴承润滑模型,主要探讨分析轴颈轴向运动对粗糙表面倾斜轴颈轴承润滑特性的影响。结果表明：倾斜轴颈轴向运动对粗糙表面径向滑动轴承润滑特性影响显著;与不考虑滑动表面粗糙度相比,考虑滑动表面粗糙度时轴颈轴向运动对轴承润滑特性的影响程度有所降低;轴颈轴向速度越小,滑动表面粗糙度对轴承最大油膜压力、承载力和稳定工作力矩影响越大;轴颈轴向速度越小,粗糙度模式对轴承润滑特性影响越显著。因此,对粗糙表面倾斜轴颈径向滑动轴承进行润滑分析考虑轴颈轴向运动的影响是非常必要的。     

Determination of the dynamic coefficients of the coupled journal and thrust bearings by the perturbation method

This paper proposes a method to calculate the stiffness and the damping coefficients of the coupled journal and thrust bearings. Reynolds equations and their perturbation equations of journal and thrust bearings are transformed to the finite element equations by considering the continuity of pressure and flow at the interface between the journal and the thrust bearings. It also includes the Reynolds boundary condition in the numerical analysis to simulate the cavitation phenomenon. The stiffness and damping coefficients of the proposed mathematical method are compared with those of the numerical differentiation of the bearing force with respect to finite displacements and finite velocities of bearing center. It shows that the proposed method can calculate the dynamic coefficients of a coupled journal and thrust bearing more numerically stable and computationally efficient than the differentiation method. It also investigates the coupling effect of the coupled journal and thrust bearing and it shows that the proposed method makes it possible to calculate the cross-coupled dynamic coefficients in the radial–axial direction of the coupled journal and thrust bearing.     

油气两相流对滑动轴承静特性影响的实验研究

在改装后的ＭＰＶ－１５００滑动轴承试验机上实验研究了油气两相流对滑动轴承承载能力及摩擦力的影响。通过对实验数据的整理发现，油气两相流对滑动轴承摩擦力影响极小，而对承载能力有一定的降低作用，但随载荷的增大，这种降低作用趋于消失。     

Comparative study of the performance of six-pocket and four-pocket hydrostatic/hybrid flexible journal bearings

This paper compares the performance of a six-pocket capillary compensated hydrostatic/hybrid flexible journal bearing to that of a simi ar four-pocket journal bearing. The comparison is based on theoretically computed results. The finite-element method has been used to obtain simultaneous solutions of the three-dimensional elasticity equations and the Reynolds equation. It is observed that the six-pocket journal bearing may be more efficient from a stability point of view as compared to a similar four-pocket journal system.

A new approach to measure the friction coefficient of micro journal bearings

A new approach and relevant test rig to measure the friction of micro journal bearings are introduced in this paper. The micro bearings under the load of milliNewton scale can be tested to indicate their tribological behavior. The test rig has the following features. (1) The separated bearing halves are attached to the journal with a soft string wrapped around them. The string is strained in a vertical line with the upper end located at a beam and the lower end hanged with a standard weight, which supplies pressure between the bearing and the journal, without bending the spindling journal. (2) The frictional force of the rotating journal on the bearing halves will result in a difference between the forces at the two string ends. (3) This force difference can be sensitively detected by strain gauges on the beam. Therefore, the micro friction between the bearing and the spinning journal can be detected and indicated.

A study of slot-entry hydrostatic/hybrid journal bearing using the finite element method

A theoretical study concerning the static and dynamic performance of hydrostatic/hybrid journal bearing compensated by slot restrictor has been presented using the finite element method (FEM). Results have been presented for a double row symmetric as well as asymmetric configurations for different values of slot width ratios (SWR) and external load ( ). In order to have a better understanding of their performance vis-à-vis other non-recessed bearing configurations, the performance characteristics of slot-entry journal bearings have been compared with that of similar hole-entry compensated journal bearings using capillary, orifice and constant flow valve restrictors for the same bearing geometric and operating parameters. The comparative study indicates that asymmetric slot-entry journal bearings provide an improved stability threshold speed margin compared with asymmetric hole entry journal bearings compensated by capillary, orifice and constant flow valve restrictors.     

On the design and development of hybrid journal bearings: a review

This paper presents a comprehensive review of developments in the design and application of hydrostatic and hybrid journal bearing systems during the last few decades. Revolutionary changes have taken place in the applications of hydrostatic and hybrid journal bearings, from very low‐speed radar to very high‐speed turbo‐machinery and ultra‐precision machine tools requiring high stiffness to improve accuracy. Hydrostatic and hybrid bearings are of interest because of their potential at very high operating speed and heavy load‐carrying capacity. This paper also outlines the analyses done of these types of journal bearings in practical application, which has led to improved bearing design. This review critically discusses the parameters that significantly affect the static and dynamic performance of a journal bearing. This review includes coverage of recent publications in the literature pertaining to hydrostatic and hybrid journal bearings focusing on the influence of parameters such as bearing geometry, supply pressure, flow control devices, fluid compressibility, fluid inertia, journal misalignment, bearing flexibility, surface roughness, and thermal effects.

Novel approach to solve the dynamical porous journal bearing problem

Analytical pressure solutions are a simple and robust way to model plain journal bearings in rotordynamics, but cannot be extended to porous journal bearings. Using the method of weighted residuals—viz. Galerkin's method with global shape functions—a novel and fast approach to solve the dynamical porous journal bearing problem is proposed. This approach allows for the influence of rough surfaces on the hydrodynamic pressure implemented through flow-factors, journal misalignment and calculation of stiffness and damping coefficients for finite bearings. The proposed method will be verified using analytical expressions and new results will be shown for porous journal bearings including the influence of rough surfaces.
