摘要
为了提高加筋板结构振动响应的预报精度,建立了考虑板的剪切变形和旋转惯性以及梁偏心的加筋板结构的振动模型,并对板的偏心情形进行了阐述,同时编制了相应的计算程序,对算例的计算精度进行了比较分析,最后将其应用于船体结构的振动响应预报,并给出了相应的计算建议.
For the goal of improving predicted precision of vibration parameters about stiffened plate, a model is built including shear deformation and moment of inertia and eccentric beam. Then a set of program is developed. The accuracy of the proposed model is demonstrated with two examples. The analysis results of ship stern structure show that the model is not only feasible and reliable, but also well suited for use in actual vibration analysis problem of ship design.
