在机械非接触密封中，微通道、微腔、微孔、织构等各种修饰的应用，引起介质层动态特性的变化。本文介绍了有关的表面形貌对合作环的振动的影响的分析结果。密封件中作用的力的平衡影响非接触操作，即保持分离环的介质层的稳定性。其后果包括：气体端面密封的模型包括非线性的Aluminold方程以及描述定子振动的动力学方程，这些方程是用数值方法同时求解的。对模型密封进行的分析和获得的结果在设计和选择设定操作条件的表面形貌时可能有用。这导致安装有这些密封件的设备的工作时间更长和操作可靠。(C)2015爱思唯尔有限公司版权所有。
The application of various modifications such as micro-channels, compartments, micro-pores, texturing in mechanical non-contacting seals causes changes of dynamic properties of the medium layer. This paper presents the results of analyses pertaining to the impact of surface topography on the vibrations of cooperating rings. The balance of forces working in a seal affects non-contacting operation, i.e. maintaining the stability of the medium layer separating the rings. The consequences thereof include: controlled leak, small wear of sliding surfaces and prolonged lifespan.The presented model of gas face seals includes the non-linear Reynold's equation as well as the equations of dynamics describing the vibrations of the stator which were solved simultaneously with the use of numerical methods. The conducted analyses of the modeled seals and the obtained results may be useful when designing and choosing surface topography to the set operating conditions. It results in longer working time and reliable operation of devices in which those seals were installed. (C) 2015 Elsevier Ltd. All rights reserved.
