| 摘 要： | 考虑密封端面液膜中的空化现象,建立了激光加工多孔端面机械密封(LST-MS)的理论分析模型,应用有限元方法研究了矩形面、椭圆面、球缺面和抛物面等4种不同型面微孔LST-MS的密封特性参数,包括端面开启力、液膜刚度和摩擦扭矩等受微孔几何结构参数的影响规律,给出了上述LST-MS在最大液膜刚度条件下微孔的最优面积密度和最优深径比.结果表明,矩形型面微孔LST-MS拥有最佳的综合性能,研究结果具有较强的理论与工程应用价值. |

| Abstract: | A theoretical analysis model was developed for a fully laser surface textured mechanical seal(LST-MS) considering cavitation within the fluid film between two faces.Finite element method was used to study the effect of geometric parameters of micropores on seal performance of a LST-MS such as face opening force,fluid film stiffness and face frictional torque.Thousands of micropores with different section profiles,such as rectangle,ellipse,globe and parabola,were fully textured by laser on one of the mating faces.The optimum values of the area density and ratio of depth to diameter of the micropores were obtained under the condition of maximum film stiffness.Results show that a LST-MS with the rectangle section profile micropores or the column micropores exhibits the best performance.The results are of important theoretical and engineering application value. |
| Keywords: | mechanical seal micro-pore face seal performance finite element method |
