A significant part of damages in end gas dynamic seals are caused by dangerous vibrations. To improve the reliability of these seals, it is necessary to develop adequate mathematical models and to perform integrated computational and experimental studies. In this article, the two-mass dynamic model for an end gas dynamic seal is considered, which is the most appropriate for practical cases. Theoretical and experimental analyses of the dynamic state of a seal have been performed. The scope of vibration amplitudes and frequencies has been determined for an end gas dynamic seal. The results can be used to design new seals and to implement seals in compressors with magnetic supports.
