摘　　要：采用沙坑回收实验和理论分析相结合的方法,对铝薄壁圆柱模拟卫星结构爆炸解体碎片分布特性进行了研究。实验结果表明,卫星模拟结构爆炸解体行为显著受壁厚和剩余燃料量影响,壁厚越小或剩余燃料量越多,爆炸解体碎片越多,且碎片质量分布范围很广,从不足0.2 g颗粒到100 g以上不规则碎片。基于实验结果,结合带壳装药爆炸解体模型和卫星弱爆炸解体模型,建立了模拟卫星结构爆炸解体碎片总数分布分析模型和碎片质量分布分析模型,为卫星意外解体碎片分布特性的科学评估提供参考。The explosion breakup debris distribution of the cylindrically simulated satellite with thinwalled aluminum alloy is researched by the sandpit retrievable experiment and theoretical analysis. The experimental results show that the explosion breakup behavior of simulated satellite is significantly influenced by the wall thickness and the residual propellant mass. The amount of explosion breakup debris increases with the decrease in wall thickness and the increase in residual propellant mass. Moreover, the explosion breakup debris mass shows a wide range from less than 0.2 g particles to more than 100 g irreg- ular debris. By incorporating the experimental results into the covered explosive explosion breakup model and simulated satellite low intensity explosion breakup model, respectively, both the amount and mass distribution models of simulated satellite explosion breakup debris are presented, contributing to the assessment of satellite breakup debris distribution characteristics in accident.
