摘要
提出了用变分有限元方法计算容器内液体晃动谐振频率的方法和步骤,这种方法可适用于各种形状复杂的容器内液体晃动问题。按照此方法对二维矩形容器问题进行了实际计算。对计算结果和解析方法获得的解进行了比较。
Calculation of resonant frequencies of sloshing in a container have been achieved by FEM with calculus of variation,which is able to solve sloshing in variety complex containers.Based on the method,a calculation of two dimensions for a rectangle container has been carried out.The numerical result shows reasonably match with analytical solution.
