based on the application in gun recoil systems,the research on the MR shock absorber under impact load is presented.

The significance of design evaluation of recoil system was introduced,and virtual prototyping model of gun was established.

The important functions of recoil system for guns were analyzed, and the necessity and significance of quantitative evaluation of its performance were demonstrated.

This paper describes the theory,structure and experiment of ER fluid application in gun recoil system.

Since magneto-rheological(MR) dampers applied to gun recoil mechanisms experience impact loads and high velocities,the impact test for the special designed long-stroke MR damper was done,and the dynamic performance of the MR damper was examined.

Based on analysis of mathematic model of gun recoil and count-recoil movement of recoil mechanism, the faults of recoil brake and its causes were simulated and calcul.

Gun recoil mechanism feasibility of taking electrorheological fluid as recoil fluid is discussed.

Influence of fluid behavior index on performance of a gun recoil magneto-rheological damper;
