【摘要】 为了提高坦克和装甲车辆的战场生存概率,提出一种气囊充气式仿形诱饵体。基于LS-DYNA有限元分析软件并采用控制体积法模拟了简化的气囊诱饵体的充气展开过程。获得了气囊充气过程中,气囊外形变化的动态结果,囊内压力和温度的变化规律;分析了气囊的热辐射特性,得到了气囊在不同温度下的光谱辐射出射度及其在3~5μm和8~14μm波段下经大气衰减后的辐射强度变化对比曲线。研究结果对仿形诱饵体的设计具有一定的参考价值。更多还原

【Abstract】 To improve battlefield survival probability of tanks and armored vehicles,a kind of airbag inflatable profiling decoy was put forward. The simplified airbag-decoy inflation process was simulated by the control volume method based on the finite element analysis software LS-DYNA. The airbag shape,pressure and temperature changes were obtained during the opening process; the heat radiation characteristics of the airbag were analyzed,the spectral radiant existance of the airbag at different temperature and the atmospheric attenuation of radiant intensity contrast curves in 3 to 5 μm and 8 to 14 μm bands were gained. The results would have a certain reference value for the design of profiling decoy.更多还原
