作为水下航行器广泛应用的一种结构，翼型极易发生流动分离现象，进而诱发流致振动问题。本文基于统计能量法开展了加强形式对翼型结构流致振动的影响研究，通过建立NACA0012翼型SEA分析模型，探究中高频段翼梁、翼肋间距等对结构流致振动的影响。研究表明，采用翼梁和翼肋结构均可有效地降低翼型结构流致振动响应，在中高频段下，随翼梁和翼肋布置间距的增加，蒙皮子系统的平均振动速度级均有小幅的下降，但翼梁结构减振效果要略优于翼肋，且两者组合减振效果更为明显。
As a structure widely used in underwater vehicles, airfoils are prone to flow separation, which in turn induces flow-induced vibration problems. Based on the statistical energy method, this study carried out the study of the influence of the reinforcement form on the flow-induced vibration of the airfoil structure. By establishing the NACA0012 airfoil SEA analysis model, the influence of the mid- and high-frequency wing spar and wing rib spacing on the flow-induced vibration of the structure was explored. Research shows that the use of spar and rib structures can effectively reduce the flow-induced vibration response of the airfoil structure. In the mid-to-high frequency range, with the increase of the spacing between the spar and rib, the average vibration speed level of the skin subsystem decreases slightly. However, the damping effect of the spar structure is slightly better than that of the wing rib, and the combined damping effect of the two is more obvious.
