Abstract

This study deals with a lightweight composite disruptor barrel used in a bomb disposal robot for a disposal operations of improvised explosive devices (IEDs). Powered by a blank .50 BMG cartridge to produce a highspeed water jet to disengage the circuit of IED, the lightweight disruptor barrel consists of an aluminum liner for water and temperature resistance and a carbon fiber reinforced polymer composite (CFRP) as a shell for main load carrying. The composite shell is fabricated by a filament winding technique to ensure a good quality of CFRP. Due to difference in water jet and regular gun firing, the internal pressure of disruptor barrel needs to be estimated by using strain gauges and high-speed data acquisition device. Then, the design phase using finite element method (FEM) simulations with smooth particle hydrodynamics (SPH) technique and material damage criteria are performed in order to optimize the thickness of composite shell and liner geometries. Finally, a lightweight composite disruptor barrel is fabricated and tested as a

拆弹机器人水射流干扰装置轻量化复合筒体设计

本文研究了一种用于简易爆炸装置(ied)排爆机器人的轻型复合干扰管。由一个空白的。50 BMG弹药筒提供动力，产生高速水射流以断开IED的电路，轻型干扰筒由一个耐水和耐温的铝制衬垫和一个碳纤维增强聚合物复合材料(CFRP)作为主要承载载荷的外壳组成。复合外壳采用长丝缠绕工艺制作，保证了CFRP的良好质量。由于水射流与常规火炮发射方式的不同，需要利用应变片和高速数据采集装置对破片筒内压力进行估算。然后，在设计阶段采用光滑颗粒流体力学(SPH)技术和材料损伤准则进行有限元模拟，以优化复合材料壳体厚度和衬垫几何形状。最后，制作了轻质复合扰流管，并进行了试验
