Integral theorem of fourier
傅里葉積分公式 -
The main work and achievements are summarized as follows : according to the spectrum analysis theory, the simple formula of the power spectrum between the excitation and the response is obtained. then the time - domain statistical properties of the structural response are acquired through fourier inverse transform, and cauchy ' s residue theorem is applied to solving the integral of fourier inverse transform, the structural dynamic reliability is calculated in terms of possion hypothesis based on first passage failure
主要研究內容如下:從譜分析理論出發,得到了激勵與響應功率譜之間的簡明關系式,由fourier逆變換得到響應的時域特徵,利用cauchy留數理論處理fourier逆變換的積分式,基於首超破壞的possion假設計算結構系統的動力可靠性,並在此基礎上進行結構優化設計,奠定了確定性模型的基礎。
