简述光纤光栅传感网络,并以四点简支长方形板为对象,建立有限元理论模型和实体模型。通过计算机模拟了其中心受力下的应变分布,并利用传感网络对其在中心荷载作用下的局部应变响应进行了监测。
The fiber grating sensing network is briefly introduced. The finite element model and the solid model are established by using the four-point simple supported rectangular plate. The strain distribution under central force was simulated by computer and the local strain response under central load was monitored by using sensor network.
