Decomposition of the Pressure Response in an ER Valve Control System

Abstract

Experimental data from tests on an ER valve pertinent to the development of a con troller for high speed machine duty has been analysed to show that three common, underlying modes of response are present. This is demonstrated for a range of industrial scale flow velocities and electrode dimensions, in the time and frequency domains. The dependence of steady-state pressure on the electric field is also discussed.
