初期通道破坏
Examples
- 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
主要研究内容如下：从谱分析理论出发，得到了激励与响应功率谱之间的简明关系式，由fourier逆变换得到响应的时域特征，利用cauchy留数理论处理fourier逆变换的积分式，基于首超破坏的possion假设计算结构系统的动力可靠性，并在此基础上进行结构优化设计，奠定了确定性模型的基础。
