Applying wavelet transform, differential equation of structural dynamic system are decomposed and dynamic parameters are described on different scales . it is proved that more information about structural damage can be acquired by multi-scale analysis based on wavelet 應(yīng)用小波變換把結(jié)構(gòu)動(dòng)力系統(tǒng)的數(shù)學(xué)方程在不同尺度上進(jìn)行了分解,得到了不同尺度上各動(dòng)力參數(shù)的描述,證明了應(yīng)用小波多尺度分析能得到更多的結(jié)構(gòu)損傷信息。
This thesis is combined with the project " identification of nonlinear structural dynamic systems and the study on structural vibration control for offshore platforms ", which is supported by national science foundation of china . based on the present situation on the vibration control for offshore platforms, this thesis studies the dynamic properties of offshore platforms under random wave loading, furthermore, proposes feedforward-feedback control strategy and h2 control method to suppress the vibration of platforms 在充分了解國內(nèi)外有關(guān)結(jié)構(gòu)振動(dòng)控制理論研究現(xiàn)狀的基礎(chǔ)上,本文考慮了海洋平臺(tái)在隨機(jī)波浪作用下所表現(xiàn)的動(dòng)力特性,及振動(dòng)控制技術(shù)在應(yīng)用于海洋平臺(tái)過程中的一些理論和技術(shù)問題,對(duì)海洋平臺(tái)振動(dòng)控制技術(shù)和一些相關(guān)問題進(jìn)行了較為深入的研究。
