【摘要】 对带弹性枪架的机枪系统动力学问题进行了分析研究，构造了机枪系统（射手、机枪、土壤系统）的二自由度动力学模型。作为实例，计算了67－2式7.62mm机枪枪身及其自动机的运动规律，并进行了实验，最后将结果作了对比分析，并对提高机枪研制水平提出了建议。更多还原

【Abstract】 Dynamic problems of a machine gun on a simulated elastic tripod mount are analysed;a dynamic model of the machine gun system (including shooter,tripod and soil) having two degrees of freedom is established.As a typical case the dynamic characteristics of a 7.62mm caliber machine gun with its automaton are analysed.Resulte of computation are compared with that of experiment,from which some proposals are presented to enhance the level of development of machine gun systems.更多还原
