在单级轻气炮上对聚酯材料的激波状态方程进行了实验研究。最高撞击速度为526 m/s，相应在靶中得到的最高撞击压力为2.14 GPa。压力测试采用锰铜计，PVDF产生的压电信号用于判读激波速度。由实验结果拟合得到了聚酯材料的Hugoniot线性关系和多项式状态方程以及Grüneisen状态方程。

The shock wave propagation characteristics of the polyester have been measured by recording the shock wave profile produced by the impact of projectiles accelerated in a light gas gun. The impact velocities in the experiments were from 323 m/s to 526 m/s, and the corresponding peaks of impact stresses in the targets were from 0.632 to 2.137 GPa. The Hugoniot relation, expressed as the curve of shock wave velocity versus particle velocity, obtained from the experiments shows linearity in the testing stress range. The polynomial equation of state is obtained by regression of the experimental data and the Grüneisen coefficient is calculated.
