| Abstract: | In this paper,a vibration self-sensing technique for magnetorheological(MR) dampers based on the measurement principle of the flux linkage of harmonic magnetic field is explored,the multiplexing of a relative displacement sensor and an MR damper and the functional integration of the vibration sensing and the controllable damping are realized,and the prototype of a magnetoelectric self-sensing MR damper based on rapid prototyping control technique is developed.The preliminary tested results indicate that the performance of the sensor of the self-sensing MR damper basically accords with that of an LVDT. |
