A STUDY ON MICRO STRAIN ELECTRORHEOLOGICAL DAMPER MODEL

摘要：

This paper presents experimental and theoretical model analysis of an electrorheological damper operating in the micro strain state. An ER shear damper is developed and installed on an established ultra-precision gas bearing stage system. The damper characteristics of force vs. velocity responses under various electric fields and excitation frequencies are obtained. To describe the practical damper characteristics, a modified Eyring-plastic model is proposed, which differ from the original Eyring-plastic model by adding a constant term. The constant term can compensate the curve error induced by the width change of the pre-yield hysteresis loop. Based on optimal parameters identification, the modified Eyring-plastic model fits the experimental data more closely. So it is more accurate to express the electrorheological shear damper characteristics operating in the region of micro strain.
