【摘要】 针对结构健康监测的实际需要,基于敏感性分析法和有效独立驱动点残差法来优化结构传感器配置,应用模糊模式识别法进行结构损伤状态评估,设计开发了智能结构健康监测系统软件ISHMS(intelligentstructural health monitoring system)。采用VC++和Matlab混合编程及多线程编程技术,通过调用OpenGL三维图形函数库进行结构建模并绘制出结构三维图形。通过161杆高精度空间桁架可变损伤模型振动实验,验证了该ISHMS软件的有效性。更多还原

【Abstract】 A software named ISHMS(intelligent structural health monitoring system) is developed to meet the engineering requirement for structural health monitoring.Sensor placement is optimized with sensitivity analysis method and effective independence driving-point residue method,and damage condition is assessed with fuzzy pattern recognition method.Hybrid programming of VC + + and Matlab and multi-threaded programming are used.To draw three-dimensional graphics of structures,OpenGL 3D graphics library is called.The test results of an intelligent space truss structure show that the proposed ISHMS is efficient and feasible.更多还原
