摘要
Previous work has indicated that electro-rheological (ER)fluid in steady valve flow can be approximately characterized by the dimensionless parameters friction coefficient, Reynolds number and Hedstrom number and the Bingham plastic constitutive equation, and has pointed towards a relationship between tests on valves of various dimensions at different excitations and speeds of flow and comparatively small volume, quick, static clutch mode tests. In this paper, the position is extended and developed more precisely. The generalized valve flow characteristic is taken, together with simple static clutch determinations of fluid yield properties, zero volt viscosity and valve dimensions to predict valve pressure/flow performance for comparison with valve test data. The static clutch test rig and test procedure are described, and the relationship between static clutch and valve flow determinations of yield stress is then further examined.
