摘要:
针对现有激波传播速度测量方法存在的问题，提出了基于光电探测原理的光探针测速方法，实现压力传感器的动态标定。分析激波在激波管内的传播规律，选用点状激光器和探测器件构建了线形探测视场，设计了信号处理电路，实现激波穿过探测区域时探测器输出信号的光电转换、放大与驱动处理。设计的电路通过模拟试验进行验证，输出的有效信号幅值不小于4V，根据区截测速原理可有效计算出激波的传播速度。
Abstract:
Aiming at the existing problems in the measurement method of shock wave propagation velocity, the paper presents a measurement method for the velocity of optical fiber, which is based on the principle of photoelectric detection and can implement the dynamic calibration of pressure sensor. By analyzing the propagation law of shock wave in the shock tube, and by using dot laser and detector is built linear detection field of view, the corresponding signal processing circuit was designed to implement that the photoelectric conversion of output signal when the shock wave through the detection area, and to amplify and drive collected signal. The simulation experiment results show that the amplitude of the effective signal of the output signal is not less than 4V. The speed of the shock wave can be effectively calculated according to the principle of section velocity measurement.
