摘要

摘要: 用作图法得到了药柱与有机玻璃隔板界面处的冲击波压力，利用AUTODYN 6.1软件模拟了药柱冲击波在有机玻璃隔板中的衰减过程，并用锰铜压力计法测量了药柱冲击波在不同厚度有机玻璃隔板中的压力，并根据理论公式计算了有机玻璃中相应的冲击波速度、波后质点速度和密度。结果表明，理论计算结果、数值模拟结果与试验测量结果一致，并根据试验结果得到了冲击波压力在有机玻璃中的衰减规律；AUTODYN 6.1软件能够准确地预测冲击波在有机玻璃隔板中的衰减特性。

Abstract: The shock pressure at the interface between booster charge and PMMA gap was calculated by graphing method. The AUTODYN was used to simulate the attenuation process of the shock wave in the PMMA gap. The output shock pressures, which were produced by the substituted booster charge of the UN gap test, were measured in the PMMA gap at different positions by manganin gauges. The shock velocity, particle velocity and density after the shock front were calculated. The results showed that the measured data, theoretical arithmetic and numerical simulation are consistent, and the attenuation regularity of shock pressure in PMMA is extracted from the test results. AUTODYN 6.1 software is capable of predicting the attenuation characteristic of shock wave in PMMA gap.
