Design and Experimental Study of Magnetorheological Recoil Device Dynamics

A magnetorheological fluid-based recoil device (MRRD) is designed. By designing the structural parameters such as the throttle bar, with the damping controllability of the magnetorheological material, a more ideal control curve is obtained, which can ensure the smallest possible recoil resistance or displacement. The magnetic circuit simulation of the designed recoil system is carried out by using the electromagnetic field finite element analysis software, and the magnetic field distribution of the recoil system under various operating conditions such as different structural parameters, saturation current and damping channels are solved and analyzed to provide a certain basis for the design and magnetic field analysis of the MRRD. The magnetorheological performance test of the system is also carried out. The calculation and test results show that the designed MRRD meets the structural and magnetic circuit design requirements and has good magnetorheological characteristics, it provides a good basis for subsequent experiments and research.
