Dynamic calibration experiments of sandwich PVDF (Polyvinylide Fluoride) stress gauges have been investigated by split Hopkinson pressure bar (SHPB). Dynamic piezoelectricity of PVDF gauges has been discussed, including testing circuit, stress concentration effect of PVDF gauge surface, inherent characteristic and package of PVDF stress gauges and multi-impact effects on the testing signals. The stress uniformity state of rubber materials has been investigated by PVDF gauges. The results show that adjusting the testing resistance can improve the accuracy; increasing the PVDF gauge sensitive area can avoid the signal distortion caused by stress concentration; thermal-plastic characteristic and gauge package can cause the PVDF stress plate to vibrate less than real signal; multi-impact has influence on both the signal loading and unloading part, but when the gauge is un-damaged, the signal flat potion is similar to the real signal.

通过夹心式PVDF(Polyvinylide Fluoride)压电计的动态分离式Hopkinson压杆(SHPB)标定实验,系统地讨论了传感器的动态响应特性,其中包括测量电路、PVDF表面应力集中、压电计的材料及结构特性和同一压电计受多次撞击对测试信号的影响,为PVDF压电计的制作工艺研究提供参考。利用标定好的压电计测试了橡胶材料在SHPB实验中的动态应力均匀过程。结果表明:调节并联电阻值可以提高压电计的传感精度;增大压电计的敏感面积可以减小因应力集中所造成的信号失真;材料的热粘塑性性质、摩擦效应等将使信号振荡幅度偏小;多次撞击对信号的加载与卸载段都将产生影响,但当传感器表面未发生明显损伤时,测试的应力平台平均值与真实信号近似相同。

通过夹心式PVDF(Polyvinylide Fluoride)压电计的动态分离式Hopkinson压杆(SHPB)标定实验,系统地讨论了传感器的动态响应特性,其中包括测量电路、PVDF表面应力集中、压电计的材料及结构特性和同一压电计受多次撞击对测试信号的影响,为PVDF压电计的制作工艺研究提供参考。利用标定好的压电计测试了橡胶材料在SHPB实验中的动态应力均匀过程。结果表明:调节并联电阻值可以提高压电计的传感精度;增大压电计的敏感面积可以减小因应力集中所造成的信号失真;材料的热粘塑性性质、摩擦效应等将使信号振荡幅度偏小;多次撞击对信号的加载与卸载段都将产生影响,但当传感器表面未发生明显损伤时,测试的应力平台平均值与真实信号近似相同。

Dynamic calibration experiments of sandwich PVDF (Polyvinylide Fluoride) stress gauges have been investigated by split Hopkinson pressure bar (SHPB). Dynamic piezoelectricity of PVDF gauges has been discussed, including testing circuit, stress concentration effect of PVDF gauge surface, inherent characteristic and package of PVDF stress gauges and multi-impact effects on the testing signals. The stress uniformity state of rubber materials has been investigated by PVDF gauges. The results show that adjusting the testing resistance can improve the accuracy; increasing the PVDF gauge sensitive area can avoid the signal distortion caused by stress concentration; thermal-plastic characteristic and gauge package can cause the PVDF stress plate to vibrate less than real signal; multi-impact has influence on both the signal loading and unloading part, but when the gauge is un-damaged, the signal flat potion is similar to the real signal.
