Linear Motion Actuator Using Magnetorheological Fluid Properties

Abstract

This paper presents a new type of actuator that uses the properties of a magnetorheological fluid. This actuator allows you to control the speed of a mechanical element and its positioning .The paper shows the conceptual model of the item, the schedule of experiments and their results. There are piston-cylinder type actuators that use magnetic fluid and have internal parts in relative motion. We propose an actuator does not have internal parts in relative motion and neither internal seals. There are shown the results obtained for the mechanical parameters of a new type of actuator with elastic elements, with linear motion. This actuator uses magnetorheological fluid properties. There are presented the constructive elements of the actuator, the properties of the magnetorheological fluid, the calculation procedure of the hydraulic and mechanical parameters and the obtained results. The results confirm the possibility of using it in various technical applications.
