【摘要】：电磁轨道炮发射过程中,受到高速滑动冲击、高温、强电磁场等极端环境影响,电枢轨道接触区域会发生烧蚀、刨削、转捩等损伤,影响发射性能和身管寿命。枢轨接触面温度分布能够反应枢轨接触状态,对提高发射系统性能和身管寿命具有重要参考价值,本文采用红外热成像法对电磁轨道炮发射过程中枢轨接触面温度及轨道散热过程进行了测试,获取了试验数据;采用有限元计算的方法得到了不同时刻枢轨接触面温度分布曲线;对比分析了仿真与测试结果,结果表明,仿真与测试数据具有较好的一致性,红外热成像技术可用于轨道炮枢轨接触面温度检测,测试数据能够用于电磁轨道炮枢轨滑动电接触特性研究。
[Abstract]:During the course of launching the electromagnetic rail gun is affected by the extreme environment such as high speed sliding impact high temperature and strong electromagnetic field and so on. The ablation planing and transition of the armature orbit will occur which will affect the emission performance and the lifetime of the tube. The temperature distribution of the contact surface of the armature rail can reflect the contact state of the armature rail, which has important reference value for improving the performance of the launching system and the lifetime of the barrel. In this paper, infrared thermal imaging method is used to measure the contact surface temperature of the central rail and the heat dissipation process of the central rail during the launching process of the electromagnetic rail gun, and the experimental data are obtained. The temperature distribution curves of the armature rail contact surface at different times are obtained by finite element method, and the simulation and test results are compared and analyzed. The results show that the simulation and test data are in good agreement with each other. The infrared thermal imaging technique can be used to detect the temperature of the rail contact surface of the rail, and the test data can be used to study the sliding electrical contact characteristics of the armature rail of the electromagnetic rail gun.
