摘要：Smart fluids have both actuating and sensing capabilities when external input fields such as electric intensity or magnetic intensity are applied. In general, studies have been conducted on smart fluids in several academy societies including chemistry, polymer, physics, and engineering. Recently, four different smart fluids, magnetorheological fluid (MRF) [1], electrorheological fluid (ERF) [2], magnetorheological elastomer (MRE) [3], and electroconjugate liquid [4] are actively being researched in various application fields. Their material characterizations are steadily investigated in terms of controllability of rheological properties such as viscosity and the field-dependent yield stress. However, for last two decades various researches using smart fluids have matured and the development of application technology using these smart fluids has been widely and rapidly undertaken by numerous researchers [5–10]. The inherent controllability of smart fluids has catalyzed broad-based research and development of many different systems including vehicle dampers, vibration control mounts, intelligent hydraulic systems, and smart robots. For the specific application, semiactive shock absorbers, utilizing MRF as the working fluid, have been successfully implemented on several passenger vehicles including Cadillac CTS-V and Ferrari FF. The primary goal of this special issue is to provide timely research in applications, devices, and systems utilizing smart fluids. Especially, this special issue focuses on new design configurations, effective dynamic modeling approaches, improvements in control efficiency, and ease of implementation along with rigorous simulation and/or experimental methodologies. Therefore, the papers published in this special issue are timely and innovative references for the development of more advanced controllable devices or systems utilizing smart fluids.
