Magnetorheological dampers (MRDs) use the controlled rheological properties of MRF with action an applied magnetic field to achieve lower current regulation and control larger damping. MRD technology is defense industry, vehicle engineering, civil traffic aerospace, other equipment. In this paper, structural design latest engineering applications three types MRDs including internal, bypass, hyb...

Magnetorheological (MR) fluid is a type of smart material that exhibits fast, tuneable, and reversible changes in its rheological properties under the influence magnetic field. It suspension small iron particles can be arranged into chains when exposed to field, resulting dramatic increase fluid's viscosity. A recent study investigated three main components MR fluid, namely soft particles, carr...

A hydraulic engine mount (HEM) is an advanced tuned mass damper (TMD) system used to isolate the noise and vibration from chassis. This paper aims design a semiactive HEM based on TMD model, which only tunes damping without affecting other lumped parameters of system. Firstly, dynamic equations modeled as are derived linear parameter model (LPM). Each analyzed identify relevant that affect damp...

The interface between the particles and carrier fluids has an important influence on performance of magnetorheological fluid (MRF). In this study, ionic liquids silicone oils with same viscosity different surface tensions were used as to prepare two carbonyl iron powder (CIP) fluids. rheological properties evaluated by MCR301 rotating rheometer. experimental results indicate that liquid-based M...

Magnetic NPs grafted via mechano-ATRP served as a powerful agent for enhancing performance and stability of magnetorheological suspensions.

according to iran’s folk medicine, camphor, a crystalline ketone obtained from essential oils of cinnamomum camphora, has both sexual behavior attenuating and enhancing properties. this study examined the effects of camphor on sexual behavior in male rats. twenty four sexually mature male sprague-dawley rats were randomly divided into 4 groups receiving daily i.p. injections of olive oil as veh...

Legacy systems engineering (LSE), the design of replacement parts and assemblies for sustaining and enabling modernization of legacy mechanical systems, is increasingly becoming essential due to excessive costs of replacing entire systems. LSE scenarios presume availability of multiple, possibly incomplete or inconsistent, sources of information, lack of digital descriptions of the parts, need ...

A magnetorheological fluid with good properties (yield stress and reversibility), containing high magnetization FeCo nanoparticles as magnetic fillers is presented.
