摘要
用解析法对立式充液圃柱壳的轴对称振动特性进行了研究.假定液体是非粘滞、可压缩的.初步探讨了液体的可压缩性、壳的几何尺寸对轴对称固有频率的影响,并给出了计算固有基频的近似公式.计算表明,对于常见的充液圈柱壳,用近似公式计算出的固有基频与解析值非常接近.
An analytical method for the computation of the axisymmetric dynamic characteristics of filled, upright cylindrical shells is presented. The liquid is assumed to be inviscid and compressible. The effects of liquid compressibility and the dimensions of shells on the natural frequencies of the axisymmetric vibrations of shell-liquid system are discussed. An approximate formula for the calculation of the fundamental natural frequency is derived with Galerkin's method. A number of numerical examples indicated that the results of analytical method are in excellent agreement with analytical method.
