摘要: 利用波动法,研究充满非粘滞不可压缩流体的,功能梯度材料圆柱壳的振动特性.相关的轴向形态用指数函数来近似,在两端简支、一端固支另一端简支和两端固支边界条件下,计及流体的影响,理论研究了壳的振动频率.通过与现有文献研究结果的比较,验证了该方法的有效性和精确性,发现二者吻合得很好Abstract: The vibration characteristics of functionally graded material circular cylindrical shell containing fluid are examined by employing the wave propagation approach. The shell was filled with a non-viscous and in compressible fluid. Axialmodal dependence was approxmiated by exponential functions. A theoretical study of shell vibration frequencies was analyzed for simply supported-simply supported, clamped-simply supported and clamped-clamped, boundary conditions with the fluid effect. Validity and accuracy of the present method was con firmed by comparing the present results with those available in the literature. A good agreement was observed between the two sets of the results.
