Title        The recoil optimization design of light gun
Abstract
Gun recoil mechanism is taken as the research object in the paper by referring to the introduction to gun recoil mechanism at home and abroad. The classification and the working principle of the recoil mechanism are described. According to the design theories, some basic parameters of the recoil mechanism which can meet the demand are gotten through primary design and calculation based on the given initial conditions with reference to the structural parameters of similar gun recoil mechanisms. Mathematical model of the moving recoil mechanism is established and dynamic simulation is done based on MATLAB/Simulink. The size of throttling bar is adjusted through the analysis and comparison of the simulation results.

Keywords gun recoil mechanism  design  MATLAB/Simulink  mathematical model  simulation  analysis and comparison of the size
