【摘要】 分形在结构损伤识别中的应用还处于理论研究阶段,还有许多基本问题亟待解决。主要有两个值得深入探讨的问题:如何从理论上证明分形应用于结构损伤识别的合理性、敏感性和噪声鲁棒性;如何在理论分析的基础上研究可行的、有效的大型结构损伤预警参数。总结了目前分形在结构损伤识别中的研究现状,分析了结构动力分频段分形动力特征,提出了广义维数保证准则。最后,展望了分形在结构损伤识别中的应用前景。更多还原

【Abstract】 The application of fractal technique to structure damage identification was in theory research phase,and some essence problems desiderate to solve.Two worth the whistle problems:how to prove the rationality and sensitiveness and stabilization of the application of fractal technique to structure damage identification;how to ascertain the feasible and effective alarm parameter of a large-scale structure.A review of structure damage identification based on fractal technique was summarized.Frequency band fractal dynamic characteristic of structural dynamic is researched.General dimension guarantee criterion(GDAC) was discussed.更多还原
