采用含金属芯压电纤维(MPF)作为传感元件,利用其传感的方向性特点,提出了一种基于MPF花形结构的冲击载荷定位方法,该方法无需知道应力波在结构中的传播速度。同时,利用该方法进行了板结构冲击载荷定位的实验研究,研究结果表明基于MPF花形组合结构的方法可以用于冲击载荷定位,而且定位精度较高。
Using the metal-core piezoelectric fiber (MPF) as the sensing element, a method based on the directional characteristics of the sensing MPF flower-shaped structure is proposed, which does not need to know the propagation speed of the stress wave in the structure . At the same time, the experimental study on the impact load positioning of the slab structure is carried out. The results show that the method based on the MPF flower-shaped composite structure can be used for the impact load positioning, and the positioning accuracy is high.
