Abstract

The paper describes the results of the parametric analysis obtained using the multibody systems. Numerical analysis allows checking different variants of the weapon without the need of building a lot of experimental models. As a part of the analysis, the impact of the slide mass, the recoil spring stiffness, the friction coefficients, the propellant gas pressure, and the force of bullet engraving the barrel on the kinematic characteristics of the weapon were checked. The extreme values of the slide mass and the recoil spring stiffness were selected, after crossing them, the correct operation of the weapon would not be possible. The operation of the pistol was checked for its multiple variants, taking into account its lubrication, lack of lubrication, and lack of friction by appropriate selection of the friction coefficients. The propellant gas pressure variants were selected to reflect the pressure in the barrel during shoot using ammunition manufactured according to different standards and of different quality. The models, taking into account the force of bullet engraving the barrel and those ignoring such force, were developed to check their impact on the kinematic characteristics of a short recoil operated weapon.
PW INKA手枪的数值参数分析
本文描述了使用多体系统获得的参数分析结果。数值分析允许在不需要建立大量实验模型的情况下检查武器的不同变体。作为分析的一部分,检查了滑动质量、反冲弹簧刚度、摩擦系数、推进剂气体压力和子弹雕刻枪管的力对武器运动学特性的影响。选择了滑动质量和反冲弹簧刚度的极值,在跨越它们之后,武器将无法正确操作。通过适当选择摩擦系数,考虑到其润滑、缺乏润滑和缺乏摩擦,检查了手枪的多种变体的操作。选择推进剂气体压力变量是为了反映使用根据不同标准和不同质量制造的弹药射击时枪管中的压力。这些模型考虑了子弹雕刻枪管的力和忽略了这种力的力,旨在检查它们对短后坐力武器运动学特性的影响。
