PVDF压力传感器在测量撞击压力中的应用

Application of PVDF Piezoelectric Transd to the Measurement of Soft Impact Pressure

采用ＰＶＤＦ压电薄膜压力传感器，测量软体低速撞击粘弹性结构的冲击载荷，试验结果表明，该传感器适用于测量软体撞击时的压力及其分布。

A technique of measuring the pressure of visco elastic structures in low speed soft impact by use of the PVDF piezoelectric transducer is developed in the paper. Experimental results show that the transducer is suitable for the measurement of the pressure and its distributions in the soft impact,and considerable accuracy of the measurement can be attained.
