新方法改进非线性气动弹性颤振分析

本文介绍了一种分析复杂动力学系统的新方法,特别关注非线性气动弹性颤振。研究提出使用Floquet Fibre Geometry和Higher-Order Reduced Coordinates来更好地理解流形外瞬态。研究表明,传统方法在准确捕捉这些状态方面存在局限性,而所提出的方法通过考虑度量法线和强稳定方向,提供了更高的准确性,从而更精确地预测系统行为。 AI

    Floquet光纤几何和高阶约化坐标用于非线性气动弹性颤振的非流形瞬态分析

    arXiv:2609.14674v1 Announce Type: new Abstract: Assigning reduced coordinates to states near an attracting limit cycle requires the correct invariant-fibre geometry. The classical first-order phase-isostable chart obtained from adjoint Floquet modes projects along the strong-stab…
