摘要/Abstract

摘要： 为研究爆炸冲击波作用于钢化玻璃产生碎片造成的次级毁伤效应，开展了钢化玻璃毁伤效应试验，进行了碎片质量分布统计。通过整理分析试验数据，得到了每发次试验碎片质量在不同飞散距离的试验统计结果。利用量纲分析，推导了碎片质量与飞散距离的无量纲函数关系式。基于该关系式，结合试验统计结果，利用最小二乘法拟合得到了碎片质量与飞散距离的半经验预测公式，并分析了公式的特点，验证了预测公式的合理性。研究结果表明，对于相同厚度的钢化玻璃，在相同破坏模式下其碎片质量分布规律一致，满足相同的分布规律预测公式。

Abstract: The secondary damage effect of tempered glass subjected to blast shock waves was researched through experiments, and the statistics of mass distribution of glass fragments were done in the experiments. The mass distribution of fragments is analyzed and researched according to the statistical results. A dimensionless function of the relationship between the fragment mass and the splashing distance is derived based on the dimensional analysis. According to the dimensionless function and the experimental statistical data, a semiempirical prediction formula to calculate the fragment mass distribution is obtained by employing the least square fit. The characteristics of the formula are analyzed, and its reasonableness and effectiveness are verified. The research result shows that the mass distribution laws of glass fragments are consistent for the tempered glasses with the same thickness in the same damage mode. Key
