| 摘 要： | 应用边界元法分析了流体非线性晃动及其对渡槽的作用效应，将所得结果与线性解析结果作了比较．数值计算表明：流体以较大幅度晃动时，线性模型结果与非线性边界元结果有较大偏差，计算有限幅流体晃动反应宜采用非线性模型．

| Abstract: | The boundary element method is applied to simulate nonlinear sloshing of fluid and dynamic effects on the aqueduct body. The results of linear wave theory and nonlinear BEM are compared. The numerical examples show that the results of linearized model and nonlinear BEM model are evidently different in the large amplitude sloshing. The nonlinear model is suggested to be used in the analysis of flnite amplitude sloshing. |
