Large Caliber Sniper Rifle Low Recoil Technology Research

Based on the comprehensive analysis of domestic and foreign large caliber sniper rifleand buffer technology status and development trend on the basis of, According to a certaintype of 12.7mm sniper rifle buffer requirements, The control rod type liquid pressure typebuffer to reduce recoil technology principle.To establish a 12.7mm sniper advanced gun interior ballistic model and aftereffect periodcalculation model, The calculated the sniper rifle interior ballistic of parameters, As thecalculation provided a basis. According to the given buffer structure requirements, putsforward the general scheme of buffer, has carried on the overall structural design. In theoverall structure, of the main components of the detailed design, To establish a buffer ofSolidWorks entity model.The gun and the buffer in motion analysis, Use of gas dynamics, classical dynamics andhydraulic transmission theory, constructs the whole gun and buffers the kinetics andmathematical model. Using Matlab software to carry out simulation calculation, the analysisof the structure of the buffer parameter to be modified, the buffer parts detailed design. Thesimulation results show that the control rod type liquid pressure type buffer scheme is feasible,The installation size limited individual carrying weapons to use, can effectively reduce thefiring process resulting in tremendous recoil. On the same type of weapon buffer design has acertain reference value.
