应用分区加权残值法对悬臂梁在一侧有水时的固有振动问题进行研究,考虑了水体压缩性的影响,导出了一般的加权积分方程式,并给出了具体的数值算例。计算结果表明,水体压缩性将进一步降低挡水结构的自振频率;对于高阶自振频率,不能略去水体压缩性的影响。
The problem of natural vibration of cantilever beams with water on one side is studied by using partition weighted residuals method. Considering the compressibility of water body, a general weighted integral equation is derived and a numerical example is given. The calculation results show that the compressibility of water body will further reduce the self-vibration frequency of water retaining structure. For high-order natural frequencies, the influence of water compressibility can not be omitted.
