Abstract:
The analogy between the wave equation of liquid and the Navier equations of structural elasticity is examined in detail. By introducing appropriate parameters, the structural counterpart of the liquid sloshing model can be easily built. Therefore, the dynamic analysis of liquid sloshing can be reduced to that of structural elasticity, and the existing FEM structural analysis computer programs can be applied to liquid sloshing analysis without any modification. The present method also reveals the internal relationship between liquid sloshing and structural vibration. The effectiveness and reliability of the method is illustrated by the numerical example.
深入分析了液体波动方程与弹性体Navier方程及其边界条件之间的对应相似关系, 运用比拟法构造了对应于液体晃动的结构弹性体模型, 将液体晃动动力问题归结为结构弹性体动力问题.算例结果与解析解的比较表明, 文中所述方法十分可靠.
