| 目的 初步探索装甲钢焊缝区的抗弹防护性能并提出防护能力提升措施。方法 通过对装甲钢焊接结构进行组织性能分析及抗弹性能测试，获得焊接对装甲车辆抗弹防护性能的影响规律，并对装甲车辆抗弹防护能力提升对策进行讨论。结果 装甲钢接头焊缝区宽度达到46 mm，焊缝中心硬度低于312HV，较母材区硬度降低40%以上;抗弹性能测试结果表明，焊缝区的抗弹性能较母材区的显著衰减，为提升装甲车辆整体抗弹防护能力，针对焊缝区薄弱点从焊接工艺控制、结构优化、加装防护组件3个方面进行讨论，并提出了相应的防护对策。结论 装甲钢焊缝区是抗弹防护的薄弱点，需通过一系列的防护措施减少焊缝区正面中弹概率，提高装甲车辆服役期间的抗弹防护能力。 |
| 英文摘要: |
| The work aims to preliminarily explore the ballistic behavior of armor steel weld zone and propose measures to improve the protection capacity. By analyzing the structure and properties of the armor steel welding structure and testing the ballistic behavior, the effects of welding on the ballistic behavior of armored vehicles were obtained. And countermeasures for improving the ballistic behavior of armored vehicles were discussed. The width of armor steel joint weld zone reached 46 mm. The hardness of weld center was lower than 312HV, which was 40% lower than that of base metal. The test results of ballistic behavior showed that the ballistic behavior of the weld zone was significantly attenuated compared with that of the base metal zone. To improve the overall ballistic behavior of armored vehicles, the welding process control, structural optimization and installation of protective components were discussed and the corresponding protective countermeasures were proposed for the weak points in the weld zone. The weld zone of armor steel is the weak point of ballistic protection. A series of protective measures should be taken to reduce the probability of being shot in the front of the weld zone and improve the ballistic behavior of armored vehicles during service. |
