WebJul 21, 2024 · Buffeting response analysis Existing theoretical and experimental studies report that the strip assumption is sufficiently accurate and the influence of the spanwise wavenumber on the AAF can be ignored in calculation and analysis for slender linear structures with large aspect ratios. Therefore, Eq. WebDec 4, 1998 · A convenient and effective finite-element-based method for buffeting analysis of complex structures is presented. This method is very efficient for structures with the natural frequencies closely spaced because their corresponding modes and the cross-correlation terms between them should be included in the mode-superposition analysis.
WebFirst, the buffeting response is estimated with a Gaussian process regression that requires less time than the traditional multimodal buffeting response estimation. Then, long-term analysis is carried out using importance sampling Monte Carlo simulations that converge faster than the traditional analysis based on numerical integration. WebApr 11, 2024 · By applying these forces to the finite element model of the suspension footbridge, a buffeting analysis was conducted by using the ANSYS Parametric Design …
WebApr 1, 2024 · The buffeting response analysis of long-span bridges under nonsynoptic events requires accurate wind field inputs [6]. The full-scale measurements of nonsynoptic wind (e.g., downburst and typhoon) present significant nonstationarity characterized by the time-varying mean and spectrum [7], [8]. WebThe increased demands of compact modern aero engine architectures have highlighted the problem of outlet guide vane (OGV) buffeting in off-design conditions. This structural response to aerodynamic excitations is characterised by increased vibration, risking structural fatigue. Investigations focused on understanding, mitigation and avoidance are …
