摘要
利用水下爆炸分析法对近场非接触爆炸载荷下的填沙水雷结构响应进行数值计算,能够得出结构毁伤情况与起爆方位、爆距的关系,估算出临界破损距离,由此可分析造成毁伤的结构运动方式,预判结构抗爆性能并给出增强抗爆性能的结构优化建议。
The structural responses of sand-filled mine under near-field non-contact explosive load by underwater explosion were calculated numerically,so as to analyze the relationships between structure damage and detonate distance and orientation,estimate the critical value of broken distance,and investigate the structural movement which caused damage.The anti-explosion performance of structures was forecasted and the structural improvement suggestions were set forth.
