鉴于在传统的水力的系统的察觉存在的问题，例如大量传感器和低测量精确性，一个新一个片目标类型流动传感器基于纤维布拉格栅栏(FBG ) 被设计并且研究。紧缩的结构被设计，它是方便的基于 FBG 的原则和目标类型流动传感器的结构的分析被拆除，处理，并且安装。在液体流动放的目标的力量被变成 FBG 波长飘移，一种相应关系地。温度和种类的生气敏感上的问题被使用相称性地在伸臂的两表面上粘贴的两倍 FBG 有效地解决。液体状态上的影响在软件通过模拟被分析流畅，并且结果证明影响比传统的结构的小。在水力的系统的实验的结果证明在在双 FBG 中央波长的变化之间有一种好线性关系，在目标表上装载的质量有一种好线性关系，并且敏感是两次单个 FBG 敏感的。

英文摘要：

In view of problems existing in the detection of the traditional hydraulic system, such as the large volume of sensor and the low measurement accuracy, a new one-piece target type flow sensor is designed and researched based on fiber Bragg grating （FBG）. A compact structure is designed, which is convenient to be dismantled, processed, and installed, based on the analysis of the principle of FBG and the structure of target type flow sensor. The force of target put in fluid flow is turned into the FBG wavelength drift, with a corresponding relationship. The problem on the cross sensitivities of the temperature and strain is solved effectively by using double FBG symmetrically pasted on the both surfaces of the cantilever. The impact on the fluid state is analyzed through simulation in the software FLUENT, and the results show that the impact was smaller than that of the traditional structure. The results of experiments in the hydraulic system show that there is a good linear relationship between the change in the dual FBG central wavelength and mass loading on the target sheet has a good linear relationship, and the sensitivity is twice that of a single FBG sensitivity.
