摘要
本文将文克尔弹性地基梁模型中的弹簧用粘弹性元件来替代,建立了三元件文克尔粘弹性地基上粘弹性梁的静力和动力本构方程,求出了粘弹性地基上弹性梁的自由振动的级数解。并且对不同的振动情况进行讨论,最后给出了算例及结论。
Static and dynamic differential equations are established for a viscoelastic beam resting upon a viscoelastic base of Winkler type with three elements by substituting viscoelastic elements for springs in the Winkler elastic beam-foundation model. Progressional solutions are obtained for vibrations of elastic beam upon viscoelastic support and various kinds of vibrations are then discussed. Example and conclusions are given in the end.
