摘要: This paper presents a phase based stiffness tuning algorithm to overcome the uncertainty of relation between magnetic current and natural frequency for magnetorheological elastomer (MRE) dynamic vibration absorbers (DVA) caused by nonlinearity MRE. The difference relative acceleration DVA mass absolute primary system was used check whether is adjusted excitation frequency. controlled difference, which made proposed not rely on model MRE DVA. Both simulation experiment demonstrate that efficient in rapidly tracking
