【摘要】 采用状态空间法给出了弹性介质中充液功能梯度圆柱壳自由振动的三维分析。引入层合模型,可以方便求解,且对任意功能梯度材料分布模型都适用。为了考虑弹性介质的影响,采用了简化的Winkler地基模型;而内流体场则采用精确方法。与已有文献结果进行了数值比较,且讨论了相关参数对自振频率的影响。更多还原

【Abstract】 A state-space approach is employed to analyze the free vibrations of buried and fluid-filled functionally graded cylindrical shells. To obtain solution, a laminate model is adopted, which is suitable for any graded materials. The effect of elastic medium is considered using a Winkler model. Numerical results are compared with existing ones and the effect of related parameters on natural frequencies is discussed.更多还原
