摘要

本文以實驗方法鑑別薄膜節流器之節流參數及薄膜順從係數，探討不同設計結構之薄膜節流器調節壓力及流量特性，實驗使用平面靜壓軸承工作台，經由測量節流器進口壓力、出口壓力及流量，使用最小誤差平方偏導數方程式聯立求解，得到薄膜節流器的節流參數及薄膜順從係數，進一步求得無因次薄膜變形係數。

This study presents the identification method of restriction parameter and proportional parameter of membrane deformation for membrane-type restrictors. The influences of supply pressure and restrictor designs on both parameters are also studied. A worktable mounting on the hydrostatic bearing is utilized to calibrate recess pressures for regulating outlet pressures of restrictors by changing the load and then both restrictor parameters can be identified from the measurements of the inlet pressure, the outlet pressure and the flow rate of a restrictor by minimizing the difference between measured and identified flow rates. Further, to get dimensionless coefficient of membrane deformation.
