| Abstract: |
| 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. |
