| 摘 要： | 提出了一种薄膜式的光纤压力传感技术,用于测量冲击波的反射超压峰值。该技术通过建立待测压力与薄膜加速度之间的正比例关系来获取压力。结合Fabry-Perot腔光学干涉测量技术,设计并加工实现了一种光纤压力传感器。开展数值模拟和激波管实验,结果证明,该压力获取技术可行,且该技术具有无须标定、制作简单、成本低廉、测量精度高、响应时间快的优点。

| Abstract: | A novel fiber optic pressure sensing technology is presented to obtain the peak reflected pressure of shock waves. This technology is based on the Newton's second law and the pressure relates directly to the acceleration of a thin diaphragm. The acceleration is detected by an interferometric measurement of the displacement using a Fabry-Perot cavity technology. Both numerical simulation and shock tube experiments prove that the pressure sensing technology is feasible. And this technology has several advantages including no calibration required, ease of manufacture, low cost, high precision and fast response times. |
