Paper Abstract
Magnetorheological (MR) fluid as a new smart material has done well in the vibration and impact control engineering
fields because of its good electromechanical coupling characteristics, preferable dynamic performance and higher
sensitivity. And success of MRF has been apparent in many engineering applied fields, such as semi-active suspension,
civil engineering, etc. So far, little research has been done about MR damper applied into the weapon system. Its primary
purpose of this study is to identify its dynamic performance and controability of the artillery recoil mechanism equipped
with MR damper. Firstly, based on the traditional artillery recoil mechanism, a recoil dynamic model is developed in
order to obtain an ideal rule between recoil force and its stroke. Then, its effects of recoil resistance on the stability and
firing accuracy of artillery are explored. Because MR gun recoil damper under high impact load shows a typical
nonlinear character and there exists a shear-thinning phenomenon, to establish an accurate dynamic model has been a
seeking aim of its design and application for MR damper under high impact load. Secondly, in this paper, considering its
actual bearing load, an inertia factor was introduced to Herschel-Bulkley model, and some factor's effect on damping
force are simulated and analyzed by using numerical simulation, including its dynamic performance under different flow
coefficients and input currents. Finally, both of tests with the fixed current and different On-Off control algorithms have
been done to confirm its controability of MR gun recoil damper under high impact load. Experimental results show its
dynamic performances of the large-scale single-ended MR gun recoil damper can be changed by altering the applied
currents and it has a good controllability.
