Title Automatic assault gun design - Recoil design
Abstract According to automatic assault guns be applied in the mountain and anti-terrorism Assault, design recoil of spring friction device to meet the requirements of automatic assault guns. Working principle of recoil of spring friction device is the use of a recoil spring for buffering and storage of energy, the use of the friction device consumes recoil energy, the use of rubber cushion pad for buffing of pediment. establishing the kinetic mathematical model of recoil basis of the recoil overall program, using mat lab write calculation procedures for solving the kinetic mathematical model of recoil when it does not consider the influence of automata and ammunition machine, having been the law of recoil displacement ，the law of recoil velocity and the law of recoil resistance. Recoil the structure and size of each part be designed with theory of mechanical tensile and theory of compression and expansion. The recoil spring is designed with a minimum length and minimum stress as the goal of "2.5 Law". Adams performed based on modeling and simulation, the results with the calculated results were compared programming.
