TÓM TẮT
Abstract Magnetorheological elastomers are intelligent materials in which many scientists have recently been interested in innovative vibration systems. MRE is made by embedding micro-sized iron particles into an elastomer such as natural rubber. MRE has overcome the disadvantages of magnetorheological fluids (MRF), such as deposition problems, leak problems, and response only under velocity. MRE-based devices have many outstanding advantages in intelligent vibration systems, such as MRE-based isolators, absorbers, and MRE sensors. Mechanical properties, espe-cially the modulus, change remarkably when a magnetic field is applied. MRE-based devices combine with a semi-active controller so that the system can avoid resonance, isolate excitation vibrations, or absorb existing vibrations. These systems can be remarkably effective in car suspension, construction sites, and mechanical systems. This paper aims to provide a comprehensive overview of MRE application aspects, including fabrication methods, properties of MREs, modeling, and applications of MREs in vibration systems.Keywords Magnetorheological elastomer ·Vibration control system ·Semi-active control
