| Abstract: | A instrument used for measuring the dynamic yield stress of EMR fluids is designed and assembled in light of the principle of simple shearing stream~([1,2]). This equipment is drived by step-motor, at the same time its precise location and velocity modulation are controlled by one chip computer and yield stress is measured by force sensor and strain tester. This instrument can be used for measuring the yield stress of ER fluids, MR fluids and EMR fluids. It is clarified by the experimental results this instrument is effective and practical with good precision in measuring the yield stress of ER, MR and EMR fluids. |
| Keywords: | ER fluids MR fluids EMR fluids instrument for measuring rheological behavior |
