摘要：

MRF actuators are new electromechanical components using Magneto Rheological Fluids (MRF). When submitted to a high enough magnetic field, MRF switch from a liquid to a near solid body. These new developed MRF actuators were developed in order to reach three aims: to offer a blocking force at rest which can be strongly reduced by applying a current, to provide an electrically-controllable resistive force over a stroke of 30 mm. to perform the control of the force in a very short time, typically in a few milliseconds. Thus, these MRF actuators can be used for two main applications: damper and latch - lock. Experiments on two versions of the actuator (a single piston rod and a feed through output axis) allows to get a blocking force around 100N, which is more than 10 times the actuator weight (its mass is 700gr). The required current and electric power required to cancel the blocking force are only 1.6A and 4W. The paper will further present the design and the electromechanical properties of the Self-breaking MRF Actuators for dampers & latches and new results on the control of these actuators.
