| 摘 要： | 提出一种利用光纤光栅传感器测量简支矩形薄板在横向载荷下挠度和应变分布的一种方法.通过在薄板4个不同位置各埋设1根光纤光栅,利用基于可调谐激光原理的光纤光栅传感解调系统检测出应变信息,并结合简支矩形板纳维叶解的前4项计算出决定挠度和应变的必要参数,最终代入矩形板各位置的坐标值即可获得矩形板各点的挠度和应变值.实验采用集中应力的方式对矩形板进行了载荷实验,实验结果与理论模拟相符,证实了该方法的可行性.

| Abstract: | A measurement method is developed to determine the deflection and strain distribution of a simply supported plane plate under transverse load.The method utilizes the strain information provided by a set of four fiber Bragg grating(FBG)sensors that are mounted on the plate in a way that all sensors measure strains along one certain direction.The sensors are interrogated using a wavelength swept fiber laser.Utilizing the strain information and the first 4 terms of Navier solution of simply supported rectangul... |
