利用高频加热的工作原理及计算机实时数据采集技术 ,在轻气炮靶室内建立了一套对靶体实现快速加热及温度实时监测的系统。解决了在低真空条件下进行冲击压缩实验所遇到的技术问题。当加载幅度约 8GPa的恒定载荷时 ,得到初始温度约 1 0 0 0K的多种材料的动态响应特性 (包括层裂强度 ,Hugoniot弹性极限 ,卸载声速等 )。实验表明 ,该系统的各项技术指标均达到了设计的要求。 Utilizing the working principle of high-frequency heating and real-time data acquisition technology of computer, a set of system to realize rapid heating and temperature real-time monitoring of target in light gas gun target chamber was established. Solved the impact of compression experiments under low vacuum encountered technical problems. The dynamic response characteristics (including the spall strength, Hugoniot elastic limit, unloading speed, etc.) of various materials with an initial temperature of about 100K were obtained when a constant load of about 8GPa was applied. Experiments show that the system’s technical indicators have reached the design requirements.
