According to gun magnetorheological (MR) recoil damper's characteristics, aiming at the recoil part of a gun system under high impact and high-speed environment, the recoil resistance force's effect on the quiescence and firing stability of the gun was studied. The controllability of a magnetorheological damper to the gun recoil part's movement was also studied. A new gun magnetorheological recoil damper was designed and developed. And a suit of real-time measuring and controlling simulation experimental platform including hardware and software for dynamic response of a gun MR recoil damper under impact load was developed. Considering the dynamic behavior of the MR damper under impact load, an in-ertia factor was introduced into the dynamic model of the recoil part of the gun system. A shock test was clone to measure the designed long-stroke MR damper's dynamic performance under impact load. To evaluate the control effect of the MR damper on the gun recoil movement during recoiling, a hardware-in-loop simulation and a test were performed. The testing results showed that the recoil's resistance and stroke of the designed gun MR recoil damper under impact load can be con-trolled by changing the applied current. The results lay a foundation for the integrated design and engineering application of the gun recoil force and stroke control.
