针对冲击波测试传感器的宽带宽要求、现有传感器种类繁多的情况,文中对江苏联能、绵阳奇石缘、美国PCB和ENDEVCO公司生产的共7种用于冲击波超压测试的传感器进行了激波管动态标定实验,分析了放大器特性和安装误差对实验结果的影响,给出了各传感器的上升时间、超调量,用参数化的建模方法求出了各传感器的工作频带,实验结果表明8530B的超调量最小,上升时间最短,8530B和113A的工作频带比其他几种要高,大量程的113A也可用于小压力的测量。

Based on high bandwidth for sensors in shock wave testing, seven sensors for shock wave overpressure testing were applied in dynamic calibration test with shock tube. Four companies including Sinocera Piezrotronics, Inc., Mianyang Qishiyuan SCI. &TECH CO. Ltd, PCB and ENDEVCO provided those sensors. The effects of amplifier characters and installing errors on experimental results were analyzed. The rise time and overshoot of each transducer were measured. The working bandwidth of five different sensors was obtained with parametric modeling. The experimental results show that the sensor 8530B provided by ENDEVCO Inc. has smaller overshoot, 8530B and the sensor 113A provided by PCB Inc. have longer bandwidth.
