Design And Analysis Of A Certain Type Of Large-caliber Sniper Rifle

Against the background of military demand of large caliber sniper rifle,taking fundamental design theory of firearms as basis,an overall design thought and design scheme of a certain kind of large caliber sniper rifle was put forward based on engineering practice and experience accumulation,type selecting and structure scheme of automatic mode,buffer mechanism and other key parts were presented;meanwhile,corresponding dealing ideas or resolving proposals were worked out combined with the critical technical problems encountered in engineering practice,and 3D structure model of the large caliber sniper rifle and finite element calculation model of the barrel vibration were eastablished;a physical prototype was developed and manufactured,and verification test was done;and finally,the technical bottleneck that restricts the development of sniper rifles was analyzed,also the development trend and direction of the sniper rifle forward was pointed out.This article could provide a reference to related employees,and the research findings could help improve the level of research and development of large caliber sniper rifles at home,thus could research and develop a better,more durable and practical high precision large caliber sniper rifle system for the front-line troops soon.
