Semi-Active Vibration Control of Magnetorheological Impact Damper

Since its performance requirements of gun recoil mechanism have been continuously increased, this paper was explored and aimed at its control method of a new type of magnetorheological gun recoil damper. Using the developed hardware-in-the-loop simulation platform for weapon system under impact load excitation and a novel large-scale single-ended MR damper without the accumulator, impact tests for the special designed long-stroke magnetorheological recoil damper were done and its dynamic performances under different impact loads and input currents were examined. Besides, its dynamic performances of MR damper under different control strategies were analyzed by tests.
