M. Whittle et al., PRESSURE COUPLING IN THE ELECTRICAL RESPONSE OF ELECTRORHEOLOGICAL VALVES, International journal of modern physics b, 8(20-21), 1994, pp. 2903-2919
An earlier model describing the electrical characteristics of an elect
rorheological (ER) valve is refined to include the effects of coupling
to the pressure response. Expressions including additional linear ter
ms in the pressure and time differential of the pressure are considere
d and it is found that a single term in the time derivative with a sma
ll time delay is quite a sufficient description of the data on the bas
is of goodness of fit.
