Non-probabilistic reliability-based robust design of micro-scale topology optimization (NRRD-MTO) for structural vibro-acoustic problem under harmonic excitation and natural frequency constraints

Multisource uncertain dynamic load identification fitted by Legendre polynomial based on precise integration and the Savitzky–Golay filters

“…In the case of an uncertain parameter's interval vector $$$ {\alpha}_i^I $$$, if $$$ \omega \left({\alpha}_i^I\right) $$$ equals $$$ \frac{{\overline{\alpha}}_i-{\underset{\_}{\alpha}}_i}{\left|{\overline{\alpha}}_i+{\underset{\_}{\alpha}}_i\right|} $$$, $$$ \omega \left({\alpha}_i^I\right) $$$ is called the uncertainty of a parameter interval vector $$$ {\alpha}_i^I $$$, which is used to quantitatively represent the uncertainty level of the interval variable 49 . The Load identification code with LPIM can be seen in Table 1.…”
