| 中文摘要: |
| 目的 分析某型导爆索组件断裂问题产生的原因。 方法 采用平板试验件模拟实际使用状态，用于考核导爆索组件的环境适应性及分离功能。 结果 试验件中导爆索组件均出现了断裂，且存在三处明显磨痕，而且有一发平板试验件的辅助限位板出现了断裂。 结论 辅助限位板刚度不足，导致导爆索组件出现疲劳断裂，增加辅助限位板厚度，可有效提高其刚度，防止断裂问题产生。 |

| Objective To analyze the cause for fracture problem of detonating cord assembly. Methods Flat plate test pieces were used to simulate the state of the actual use, to assess the environmental adaptability and separation function of the detonating cord assembly. Results Fracture occurred in the detonating cord assembly of all test specimens, and there were three obvious wear scars, and the auxiliary limit plate of 1 tablet test piece fractured. Conclusion The auxiliary limit board had insufficient stiffness, which led to the fatigue fracture of the detonating cord assembly. Increasing thickness of the auxiliary limit board could effectively improve its rigidity and prevent the fracture problem. |
