摘要 描述了对爆炸驱动金属管膨胀的理论计算并通过实验对其进行了验证。利用力学模型和经验公式计算不同材料和尺寸的金属管的爆轰参数:膨胀角、破裂半径和爆速。采用高速分幅相机测试技术,得到了金属管膨胀运动过程的分幅照片,掌握了金属管的膨胀及破裂情况,由此测得了膨胀角,并使用电探针测量了炸药爆速。通过与实验金属管的膨胀数据对比,为理论计算可靠性提供重要依据。 Cylindrical Tube Under inside-explosive Loading is investigated in theory and mathematical results are put forward as well as sustained by experiment. Parameters of Cylindrical Tube . different sizes and materials are got including expansive angle,fracture radius and detonation velocity. The cylinder expansion processes were recorded by rotating mirror streak camera. The photos of camera were analyzed by the computer image technique. Detonation velocities of explosives were measured by electric pins. All the data from experiment can be important proof for the reliability of the mathematical study.
