摘　　要：为了分析复进簧刚度及预压力参数对枪支射速的影响,建立了自动机在复进簧作用下的后坐及复进过程数学模型,建立了某典型冲锋枪虚拟样机仿真模型。通过对数学模型的理论分析及虚拟样机模型的仿真分析,获得了弹簧刚度及预压力对自动机后坐复进总时间的影响曲线。分析发现,在弹簧刚度及预压力较小的情况下,枪支射速随弹簧刚度及预压力增大而增大,而在弹簧刚度及预压力较大的情况下,结论正好相反。In order to analyze the influence of the stiffness and pre-pressure of the Multiple spring on the gun firing rate,the mathematical model and virtual prototype simulation model of a typical submachine gun was established.Through the theoretical analysis of the mathematical model and the simulation analysis of the virtual prototype model,the influence curve of spring stiffness and pre-pressure of the automaton was obtained.It is found that when the initial spring stiffness and pre-pressure are small,the gun firing rate increases with the spring stiffness and pre-pressure,while when the initial spring stiffness and pre-pressure are large,the conclusion is just the opposite.
