为考核装甲车辆用防爆复合结构的抗爆性能,提出了基于底甲板损伤等级和(AIS)人体伤害/防护等级为防爆判据的台架试验方法和模拟舱体试验方法.建立了防爆复合结构抗6 kg TNT当量的试验平台,并进行了防爆复合结构抗6 kg TNT当量爆炸性能验证试验.台架试验后基板的稳态变形量为 47.451 mm,模拟舱体试验后舱内模拟假人各项关键部位测试结果均在指标范围内,这表明该防爆复合结构具有良好的抗爆性能,对装甲车辆底甲板具有一定的保护作用,并且能够有效保护模拟舱体内部人员.此外,上述试验结果还表明,提出的台架试验方法和模拟舱体试验方法能够较好地考核和评价装甲车辆用防爆复合结构的抗爆性能.
Research on explosion-proof composite structure anti-explosion performance test technology for armored vehicles
In order to evaluate the anti-explosion performance of explosion-proof composite structures for armored vehicles,a bench test method and a simulated cabin test method based on the explosion-proof criterion of bottom deck damage level and human injury/protection level were proposed.A test platform for explosion-proof composite structure resistant to 6 kg TNT equivalent was established,and the anti-explosion performance verification test of explosion-proof composite structure with 6 kg TNT equivalent was carried out.The deformation of the substrate after the bench test is 47.451 mm,and the test data of the simulated dummy in the cabin after the simulated cabin test are within the damage threshold,which show that the explosion-proof composite structure with 6 kg TNT equivalent have good anti-explosion performance,have a certain protective effect on the bottom deck of the armored vehicle,and can effectively protect the personnel inside the simulated cabin.In addition,the above test results also show that the proposed bench test method and simulated cabin test method can better assess and evaluate the anti-explosion performance of explosion-proof composite structures for armored vehicles.
