轴膜

Spikelets dorsally compressed, florets 1 or 2, disarticulating above glumes and between florets, rachilla extension with apical rudimentary floret present; lower glume minute or suppressed; upper glume leathery, appressed to rachis, exceeding and covering the sunken florets, closely 5–12-veined, apex acute to caudately awned; lemma much shorter than upper glume, rounded on back, cartilaginous to hyaline, 3-veined, apex obtuse to acute; palea membranous, usually equal to lemma.

背小穗压扁，小花1或2，脱节高于颖片和在小花，小穗轴扩展具顶端不发育之间宿存；压抑的更低的颖片小或；上面颖片革质，贴伏于轴，超过和包括沉没的小花，接近5-12脉，对具芒caudately先端锐尖；外稃远短于上面颖片，在后面，对透明，3脉，先端钝的到锐尖软骨上绕行；内稃膜，通常等于外稃。

, after the axle journal begins to rotate, the characteristic angle of oil film and the original geometric angle of pad have the following relationship

由图1可知，轴颈开始旋转后，油膜特征角与瓦块原始几何角有如下关系

, when the eccentricity is equal to zero, the arc centre of pad and the centre of axle journal are coincident, and the thickness of oil film is constantly C.

当偏心率为0时，如图5所示，瓦块圆弧中心与轴颈中心重合，油膜厚度恒为半径间隙，根据流体润滑理论，无动压效应，压力为0，瓦块摆角为零。

It is clear that, when a tilting pad is in static equilibrium, the tilting angle is related to the parameters of pad, clearance ratio as well as initial eccentricity, and unrelated to the speed of axle journal, viscosity of oil film, etc.

可见，可倾瓦瓦块达到静平衡时，其摆角与瓦块参数、间隙比及原始偏心率有关，而与轴颈转速、油膜粘度等参数无关。

It is very important to understand the effect of oil film reformation and rupture boundary condition on the journal bearing performance when journal, bearing block perturbation and inlet oil pressure exist.

由于轴颈、轴承扰动的作用和进油压力的不同，油膜形成和破裂边界也发生相应的变化，因此有必要研究上述变化对轴承性能的影响。

Oil film reformation and rupture boundary conditions change with the journal, bearing block perturbation and inlet pressure.

由于轴颈、轴承扰动的作用和进油压力的不同，油膜形成和破裂边界也发生相应的变化，因此有必要研究上述变化对轴承性能的影响。

Based upon SIMPLEC algorithm of CFD analysis, air film flow in the oil-free air bearing is simulated to illustrate its working principle, as well as performance's influence from air compressibility, shaft eccentricity ratio, clearance size and rotating speed.

基于计算流体动力学中的SIMPLEC算法，从流动模拟分析的角度对动压气膜轴承的工作机理，包括气体可压缩性，轴承间隙大小，轴颈偏心率及轴承运行线速度的作用等作了分析。

At the same time, for the polishing plate of diamond film with the same thickness, von Mises equivalent stress and the radial displament show a ascending tendency with the increase of rotating speed, but the axial displacement firstly increases and then decreases.

同时，对于同一厚度的金刚石膜抛光装置，随着转速的提高，von Mises等效应力和径向位移呈现相似的上升趋势，轴向位移却先上升后下降。

Based on lubrication analysis of journal bearing, the stress distribution of shaft was calculated by using film pressure that calculated as boundary condition of load.

在轴承润滑分析的基础上，将得到的轴承油膜压力作为载荷边界条件，计算了轴的应力分布。
