枪榴弹引信发射冲击响应特性研究

枪榴弹发射过程中引信爆炸元件常在隔爆位置提前发火爆炸。应用应力波理论对枪榴弹引信发射过程的应力波传播问题进行了研究。将应力波在捕弹器和引信中的传播作为一维应变平面波来处理，运用杆中一维应力波中有关弹性纵波的理论，建立了由不同材料组成的应力波传播模型，详细探讨了在捕弹器捕获枪弹这一极其短暂的过程中，引信体或垫片结构尺寸、材料和位置参数等因素对引信爆炸元件中应力波传播的影响规律。

Research on Firing Shock Response of Rifile Grenade Fuze

The explosive components in the fuze are often preignited in the interruption position during firing of rifle grenade. The propagation of stress wave during the firing cycle based on stress wave theory was studied. The stress wave, propagated along the bullet trap and fuze, was treated as plane wave of linear dimension strain. The model of stress wave propagating along different materials was established according to the elastic longitudinal wave theory of bar. The various factors having efect on the propagation of stress wave, such as the structural, material and positional parameters of the fuze and gasket on the process of trapping bullet were analyzed in detail.
