THE CALIBRATION AND INTERPRETATION OF RECORDED SHOCK-TUBE PRESSURE DATA USING PIEZOELECTRIC SENSORS,

摘要

This report is intended to serve as a guide,or basis,for the calibration and analysis of recded pressure data. Many of the techniques and areas covered are also applicable to other types of gages; i,e.,strain,velocity,acceleration,etc. Photographs of typical shock-tube data are generously used to familiarize the reader with the actual appearance of the true pressure pulse which has been modulated by the effects of resonance,overshoot, groundloops,inadequate bandwidth,and poor gage isolation.
