最近关于非接触式柔性安装转子 (FMR) 密封件动力学的理论研究表明，与柔性安装定子 (FMS) 密封件相比，它在动态行为的各个方面都更优越。无论运行速度如何，FMR密封本质上都是稳定的，最大相对不对中响应较小，临界定子不对中较大。所有这些都是卓越绩效的衡量标准。这项工作对非接触式 FMR 密封件的动态行为进行了实验研究。 FMR 密封件的稳态响应在各种操作条件下进行了测量。结果以动态和静态传递率的形式给出，即对两个力输入的响应幅度比：初始转子和固定定子不对中。然后将这些结果与分析预测进行比较。此外，针对每组操作条件绘制了操作图。这些地图显示了密封件运行的安全程度（远离接触）。结果表明，最大化流体膜刚度的密封参数组合对于安全非接触操作来说是最佳的
Recent theoretical work on the dynamics of the noncontacting flexibly mounted rotor (FMR) seal has shown that it is superior in every aspect of dynamic behavior compared to the flexibly mounted stator (FMS) seal. The FMR seal is inherently stable regardless of the operating speed, the maximum relative misalignment response is smaller, and the critical stator misalignment is larger. All these are measures of superior performance. This work undertakes the experimental investigation of the dynamic behavior of a noncontacting FMR seal. The steady-state response of the FMR seal was measured at various operating conditions. The results are given in terms of dynamic and static transmissibilities, i.e., amplitude ratio of responses to two forcing inputs: the initial rotor and fixed stator misalignments. These are then compared to the analytical predictions. Further, operation maps are drawnfor each set of operation conditions. The maps indicate how safely (away from contact) the seal operates. It is shown that the combination of the seal parameters that maximize the fluid film stiffness is optimal for safe noncontacting operation
