A high-speed reciprocating mechanism is described in order to provide
the basis of a general investigation into the required properties of e
lectro-rheological fluids and associated materials for use in flexible
, inertial mechanisms. The dynamic model of this, when run for realist
ic existing machine requirements clearly illustrates the need for a fu
lly integrated approach to high speed machinery design. The work sets
quantified targets and draws attention to the need for the continuing
development of improved electro-rheological fluids which will have hig
h yield stresses with acceptable viscosities and the conditions they m
ust operate under: high shear rates, centrifugal loadings and accelera
tions.
