Abstract

In the past decades, there have been a number of research activities to control unwanted vibration of flexible robot arms. The electrorheological (ER) adaptive structures, which behave as viscoelastic damping structures with controllable shear modulus, are used to suppress the residual vibrations of the rotating flexible arm in this study. The flexible arm is designed as an ER sandwich structures, in which ER fluids is sandwiched between two elastic surface layers. Experimental tests are conducted. The vibration response performances of the beam subjected to different electric field intensity and motion conditions are demonstrated and evaluated. The experimental results obtained indicate that significant vibration attenuation is achieved at different operating conditions by applying an electric field to the rotating flexible arm.
