摘要:
文章首先综述了目前主要的涡振幅值估算方法，从理论基础上分析比较了各自的特点及应用范围。然后以1组大长细比匀质构件的实测涡振幅值数据为基础，对比研究了各种估算方法的效率，重点观察了高阶涡振幅值的估算情况。实测涡振幅值数据与经验估算值的对比分析结果显示基于简谐力涡激力模型推导的Ruscheweyh估算方法适用性强。最后，通过对1座柔性桥梁的涡振幅值进行估算并与现场实测值对比，分析总结了现有涡振幅值估算方法在该领域的应用局限性，并对今后的研究方向做了展望。
Abstract:
The prevailing Vortex-induced vibration (VIV) amplitudes estimation methods are introduced, whose theoretical basis and application limits are comparatively analyzed. Their prediction efficiency on VIV amplitude are examined based on a group of practically measured VIV data, which belongs to several constant cross section slender structures, and the prediction on high mode VIV amplitudes of structures are specifically highlighted. The comparison between practically measured VIV amplitude and empirical prediction data proved that the Ruscheweyh method is the most effective one. Finally, the research status of VIV amplitude estimation on flexible bridges is concluded through the application of the prevailing methods on a real bridge's VIV data. The research difficulties in this field are summarized and further works are generally summoned.
