TC材料的低压Hugoniot参数实验测量研究

Low-Pressure Hugoniot Parameters Measurement of TC Material

采用高阻值锰铜压阻传感器,并通过一级轻气炮实验对TC材料的低压Hugoniot参数C0,λ进行了测量,实验得到的压力曲线与理论分析基本一致,并对压力曲线与密实材料的理论波形进行了比较和分析。通过对实验结果进行最小二乘法拟合,得到了该材料低压冲击时的Hugoniot压缩线以及低压Hugoniot参数C0,λ。拟合结果表明:该多孔材料的低压D-u线具有较大的分散性。

Low-pressure Hugoniot parameters C0 ,λ of TC material were measured using high resistance manganin gauge and light-gas gun experiment, the pressure curve gained by experiment is consistent with theory analyze, compare and analyze the pressure curve gained by experiment with theory wave- shape of dense material. The low-pressure Hugoniot curve and parameters C0 ,λ were gained by fitting the experiment results using the least two-multiply method. The fitting results indicate. The low- pressure D--u curve of TC material has a great dispersive.
