| 摘 要： | 为了研究超高速碰撞产生的闪光强度特征，利用建立的光学高温计测量系统并结合二级轻气炮加载系统，进行了2种实验条件下的超高速碰撞实验。每组实验使用2组光纤探头，1组为直接对准碰撞点安装，另1组为侧向对准碰撞点安装。通过实验所获原始数据的分析表明:在给定实验条件及光纤探头安装方案下，在405~633 nm波长范围内超高速碰撞2024-T4铝靶产生的闪光强度峰值随波长的增大而增强；在波长为667 nm附近闪光强度峰值减小。

| Abstract: | In order to investigate the characteristics of light flash intensity produced by hypervelocity impact, experiments on hypervelocity impact of 2024-T4 aluminum target were conducted under two kinds of experimental conditions by using an optical pyrometer measurement system established and a two-stage light-gas gun loading system. Two sets of optical fiber probes were used in every experiment: one directed to the impact point, and the other laterally directed to the impact point. Under the given experimental conditions and optical fiber probe schemes, the analysis of acquired original data show that the peak value impact light flash intensity increases with the wavelength increasing in the range from 405 to 633 nm during the hypervelocity impact of 2024-T4 aluminum target, and it d |
