Abstract

A comparative analysis of the characteristics of various piezoelectric transducers for measuring pulse pressures was performed. Their sensitivity and response time were determined, and the effects of the steady-state temperature and pulsed heat flows on the measurement results were investigated. The conditions for the linearity of characteristics under the experimental conditions were established. The conditions were determined for observing the “thermal zero drift,” which characterized the influence of thermal heating on the output data of pressure transducers. The investigations were carried out in a shock tube, at a special calibration test bench, and at a test bench that generated the stepwise pulse of the radiant heat flow.

各种压电式压力传感器特性的比较分析
对各种脉冲压力测量压电换能器的特性进行了比较分析。测定了它们的灵敏度和响应时间,研究了稳态温度和脉冲热流对测量结果的影响。在实验条件下,建立了特性线性化的条件。确定了观察“热零漂移”的条件,该条件表征了热加热对压力传感器输出数据的影响。研究分别在激波管、专用校准试验台和产生辐射热流阶跃脉冲的试验台进行。
