| 摘 要： | 研究水下双层圆柱壳体振动传递特性具有重要的工程意义,尤其对于水下结构噪声快速预报和外壳表面速度场实时重构.以此为出发点,通过双层加肋圆柱壳体模型水下振动试验研究了不同激励条件下内外壳体振动特性;然后建立了水下双层圆柱壳体有限元模型,计算分析了壳体在流固耦条件下的振动路径及特性,找出了不同激励方向、流体耦合方式和内外壳体连接方式等典型因素下内、外壳体间振动传递规律,为速度场重构和水下噪声预报提供了一定的理论指导.

| Abstract: | In order to reconstruct velocity field and evaluate noise on outer shell surface of a submarine,vibration transmissibility between double shells of a submerged cylindrical double-shell structure was studied with underwater vibration test.An finite element model of a ribbed cylindrical double-shell was established here,its vibration response was analyzed.The law of vibration transmissibility for cylindrical double-shells in different forms was found,with typical influencing factors of fluid-structure couplin... |
