| 摘 要： | 优化算法在用于结构的物理参数辨识时,测量数据的不完备和噪声严重影响了参数的辨识精度.针对这一问题,为得到理想的辨识精度,将时程响应数据和频率数据定义为多目标函数,并利用多目标差分进化算法(DEMO)进行优化求解.在数值模拟中,利用10层剪切型框架结构和31个单元的桁架桥结构作为算例.计算结果表明,该多目标函数和DEMO...

| Abstract: | Using optimization algorithms to identify structural physical parameters,the identification precision is seriously influenced by incomplete measurement and noise.In order to solve this problem,a new multi-objective function defined by dynamic responses and frequencies was proposed,and the Multi-objective Differential Evolution Optimization(DEMO) was used to obtain optimal solutions.In numerical simulation,a 10-floor shear structure and 31 elements truss structure were identified,and the results proved that ... |
