This research is focused on evaluation of the magnetorheological fluids (MRFs) based damper which works in squeeze mode. The operation direction this parallel to external magnetic field. Before testing, commercial software ANSYS was used analyze field distribution inside generated by charging current coil. performance tested using MTS809 (produced MTS Systems Corporation, USA). For simulation damper, a mathematical model set up. Experimental results showed that small squeezed MR could...
In this paper, a novel magnetorheological (MR) damper working in the squeeze-valve bi-mode of MR fluid (MRF) was developed. The consisted two parts: valve part and squeeze part. Both parts could provide damping force when worked. Firstly, model established to ensure that structure suitable for our design. Then, magnetic field distribution inside simulated. simulated results showed flux density 120 mT current coil 2.0 A, uniform at area MRF. be controlled by changing coil. Finally, fabricated...
In this work the experimental investigation of magnetorheological fluids in squeeze mode has been carried out under constant volume with a self-developed device. The were forced to move all directions horizontal plane as two flat surfaces came together. A pair Helmholtz coils was used generate uniform magnetic field compression gap. normal forces within gap systematically studied for different field, velocity, particle concentration, viscosity carrier fluid and initial distance. Two regions...
In this research, the influence of additives on rheological and sedimentary properties magnetorheological fluid (MRF) was tested analyzed. The were stearic acid, sodium dodecyl sulfate (SDS), their mixture, respectively. MRF composed carbonyl iron particle, silicone oil, liquid paraffin, graphite bentonite, SDS. results indicated that mainly influenced by mass fraction particle. When fractions particle additive same, shear stress with acid larger than SDS, maximum increment 73.81%. 40–50%,...
Abstract A reinforcing method for developing a kind of shear wall with both excellent self-centering capacity and high energy dissipation was presented, in which carbon fiber reinforced polymer (CFRP) bars or steel strands were longitudinally placed to provide restoring effect, while magnetorheological (MR) dampers externally coupled panels extra dissipation. To verify the feasibility this method, three slender concrete walls tested under reversed cyclic lateral loading subjected constant...
The MR effect of an Fe<sub>3</sub>O<sub>4</sub>-immobilized-SiO<sub>2</sub>-nanosphere based magnetic fluid was 25 times larger than that Fe<sub>3</sub>O<sub>4</sub>based fluid.
Magnetorheological Elastomers (MREs) are smart materials with the ability to modulate their mechanical properties by changing external magnetic fields, offering extensive potential for applications requiring variable stiffness and damping devices. A comprehensive model that explains influence of loading conditions on performance MRE is crucial understanding intrinsic mechanisms during operation, design, analysis, improvement intelligent energy dissipation vibration control devices based MRE....
Magnetorheological (MR) damper was a kind of smart instrument, and it very suitable for the semi-active control. In this research, large-scale MR working in shear mode fluid developed to enhance mechanical properties wall. The influence on walls, such as stiffness, strength, ductility, energy dissipation capacity, had been researched. Firstly, both model wall were established optimize Then, three different concrete walls fabricated, which reinforced by carbon fiber-reinforced polymer (CFRP)...
In this work, the influence of oscillatory shear on magnetic field dependent electric conductivity magnetorheological fluid (MRF) was reported. Upon applying a 0.96 T field, could increase about 1500 times larger than one without field. By increasing volume fraction carbonyl iron particles in MRF from 5% to 30%, increased 565 times. Under an shear, resistance decreased and it oscillated synchronously with shear. Interestingly, strain led amplitude resistance. A particle–particle model...
Abstract This work concerns the special conformational behaviors for di‐substituted cyclohexanes that inherently depend on spatial orientations of side chains in flexible cyclic ring. The 1,3‐dimethylcyclohexane and 1,4‐dimethylcyclohexane both cis ‐ trans ‐configurations were focused here to unravel their inversion‐topomerization mechanisms. Full geometry optimizations separately performed at B3LYP/6‐311++G(d,p) MP2/6‐311++G(d,p) levels explicitly identify all distinguishable molecular...
Objective To investigate the changes of bone metabolic index and their influencing factors in patients with Graves disease (GD) Gejiu. Methods 112 cases newly diagnosed GD Gejiu were selected. The levels blood calcium (Ca), phosphorus(P), 25-hydroxy vitamin D[25(OH)D], alkaline phosphatase (ALP), tartrate resistant acid (TRACP), parathyroid hormone (PTH), creatinine (Cr) other indicators detected. Group comparison was made according to gender, age 25(OH)D deficiency, multivariate...

Abstract PurposeEsophageal cancer (EC) is the sixth leading cause of death worldwide. Esophageal squamous cell carcinoma (ESCC) a predominant subtype EC. Identifying diagnostic biomarkers for ESCC necessary practice. Increasing evidence illustrates that apolipoprotein C-1 (APOC1) participates in carcinogenesis. However, biological function APOC1 remains unclear. Patients and methodsWe investigated expression level using TIMER2.0 GEO databases, prognostic value Kaplan-Meier plotter TCGA...
