| 摘 要： | 本文利用光纤布拉格光栅(FBG)的智能感知特性研制开发一种复合材料结构,用以汽车的动态称重.采用轴荷称重的方法进行动态称重,其基本思想是将光栅布设在称体结构的承重梁上,利用光栅监测称体的变形,根据己知系统的动态特性和实测的动力响应,即称体的变形,反算出结构所受的动态激励,从而获得汽车载荷.首先,基于光纤传感器的原理和称重结构的力学特性,推导出载荷识别的算法.对称重系统进行动态实验,结果表明了以上算法的合理性,并对误差进行了分析.

| Abstract: | Composites structure for dynamic weighing of the traffic is developed by using the sensing properties of Fiber Bragg Grating(FBG).The method of axes weight is applied.The main idea of weight-in-motion systems is based on the principle that the deformation of weighing system can be gotten from the main beam with the FBG strain sensors.The dynamic excitation can bederived according to system dynamic character and actually measured power response,namely,the deformation of weighing system.Accordingly,the traffi... |
