Dynamic Characteristics of Magneto-rheological Fluid Actuator for Micro-motion Control

Output Torque Modeling of a Magneto-Rheological Based Actuator

Recent research intended to integrate robots into the anthropic domains has introduced a new set of challenges with regard to design and control of such robots. Among these challenges, human safety is perhaps one the most predominant issues. While, existing solution relies on highly specialized and high cost actuation mechanisms, a new generation of intrinsically safe robots (manipulators) that...

Simulation of the Dynamic Behavior of the Magneto-rheological Engine Mount for Automotive Applications

A Rheological Model for Magneto-rheological Fluids

Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...

Discrete-time Dynamic Model of a Magneto-rheological Damper for Semi-active Control Design

Semi-active control systems have been widely studied over the last 20 years. The range of applications includes automotive suspensions, seismic vibration mitigation, large bridges vibration control, knee prosthesis, among others. Semi-active actuators have a complex dynamics, and interaction between actuator and plant cannot be ignored in control design. This is specially true for magneto-rheol...

Review on magneto-rheological fluid and its application

Magnetorheological fluids have received widespread attention as smart materials due to their tunable properties. MRF consists of three key components including, soft magnetic particles, carrier liquids, and additives. This review details the characteristics, composition, and rheological principle of MRF, working principle of MRF devices, and their applications in other engineering arenas. The a...
