And a modified frequency coefficient considering shear lag is put forward. It is demonstrated that this method which is applied in one dimension beam vibration characteristic calculation of ship hull vibration calculation and proved by 11000t tanker is feasible.
本文通过构造的薄壁箱型梁模型,分别运用一维和三维空间Timoshenko梁模型计算其固有频率,并对两种模型的计算结果进行比较,探讨了剪切滞后效应对一维梁模型固有频率的影响,提出一种考虑剪切滞后影响的频率修正系数,并将此修正系数应用于船舶总振动计算的一维梁模型中,用110000t油轮进行验证,计算结果证明本文方法是可行的。
