| 摘 要： | 为了对比分体串联与单级装药水中爆炸对目标结构的作用效能,根据弹塑性动态力学理论分析了串联装药水下爆炸作用下固支方钢板的动态响应,完成了不同装药质量比的水下爆炸冲击作用实验.结果表明,在总装药量相等条件下串联装药水下爆炸对固支方板的作用效果明显优于单级装药的作用,变形挠度最大可提高36%.实验和理论分析结果有较好的一致性.

| Abstract: | A tandem charge structure of torpedo warhead is designed.The dynamic response of clamped square steel plates under underwater exploding loading of tandem charges is analyzed based on the elastic-plastic dynamic theory.Several underwater exploding tests of the tandem charges with different front-rear weight ratios have been carried out.The results showed that the centre displacement of clamped square steel plate of the tandem charges is much larger than those of single charge in the condition of the same tot... |
