摘要
设计了低压锰铜压阻传感器 ,并通过平板撞击实验标定了该传感器在 0 .3~ 9.4GPa范围内的压阻关系。标定曲线在 0 .3~ 1.5GPa范围内是线性的 ,对应的是传感器的弹性状态 ,而在 1.5~ 9.4GPa范围内是二次曲线。标定曲线的拐点在 1.5GPa附近 ,这与理论分析和他人的实验结果相接近。
High resistance foil like manganin gauge for lower shock pressure measurement was designed and calibrated in a series of planar shock wave experiments. The calibrated curve obtained is linear in the range of 0.3~1.5 GPa and quadratic for higher stresses (1.5~9.4 GPa). The linear portion is attributed to the elastic behavior of the gauge. The inflexion of the curve was found to be at 1.5 GPa and is in accordance with the other’s experiment result.
