【摘要】 建立结构损伤诊断子系统是建立大型工程结构智能健康监测专家系统的核心问题。人工神经网络技术可以实现结构损伤的自动识别与定位,具有广阔的应用前景。本文介绍基于人工神经网络的两级损伤识别策略,并对采用人工神经网络进行结构损伤诊断的网络输入参数与网络结构选择等关键问题进行了探讨。更多还原

【Abstract】 The sub-system of structural health diagnosis is key part of the intelligent health monitoring expert system for large-scale structures.The occurrence of the damage may be indicated automatically by the technology of damage identification with artificial neural network,while the location of the damage may be determined.So the technology has bright prospect.The two phase identification strategy based neural network is produced in this paper.At the same time,the choices of input parameters for networks and construction for networks that are the important problems in structural damage diagnosis with artificial neural network have been discussed.更多还原
