SHPB波形整型器实验研究

The experimental research on SHPB waveform dresser

通过实验研究了不同材料对入射波形的改善效果,测试结果表明:1 mm厚铜片、2 mm厚铜片以及多层叠加的锡箔纸作为波形整型器时入射波下降沿略有延长,改善效果并不明显;使用麻布作为波形整型器时可以明显的减弱波峰的震荡,并且延长波形下降沿至60μs左右;使用黄油作为波形整型器时可以明显的延长波形下降沿,但获得的入射波形不稳定。

This paper researched the improving effect of different materials to incident wave through the test, the test results showed that： the in- cident wave falling edge slightly extended, the improved effect not obvious taking 1 mm thick copper, 2 mm thick copper and multi-layer foil as waveform dresser; using linen as waveform dresser could obviously weaken the peak shock, and the extend waveform serious decline to about 60 μs; using butter as a waveform dresser could obviously prolong the waveform falling edge, but the gained incident waveform instability.
