摘 要:为了满足大口径无后坐力爆炸物销毁器一体化、轻量化设计要求,建立一种基于非线性有限元方法的无后坐力爆炸物销毁器瞬态动力模型。依据无后坐力爆炸物销毁器两端对称的结构特点和膛压变化过程,理论分析了其身管强度,并采用非线性有限元方法,对身管整体强度进行数值仿真及验证。结果表明:新型无后坐力爆炸物销毁器身管在一体化设计的前提下,整体强度满足材料弹性极限要求,并且具有足够的安全系数,弹仓部可以减少其壁厚,以实现其轻量化。该研究为大口径无后坐力爆炸物销毁器和排爆机器人身管的设计提供理论依据。In order to meet the requirement of the integration and light weight design on the recoilless improvised explosive device (IED), the transient dynamics model was established by the nonlinear finite element method. According to the symmetrical structure and chamber pressure of the recoilless IED disruptor, the strengths were obtained by the theoretical analysis and verified by the nonlinear finite element model. The results illustrated that the maximum strength meets the material elastic limit requirement and the thickness of the tube could be diminished under the requirement of the light weight, which provided theoretical foundation for the heavy caliber recoilless IED disruptor and explosive ordnance disposal (EOD) robot.
