| 摘 要： | 基于ABAQUS和ANSYS平台，以某水电站⑤号机进水口坝段为例，建立了拦污栅框架的独立模型和“拦污栅框架-进水口”耦联动力分析模型，对进水口及拦污栅框架的动力特性进行了分析，总结了主振型规律，并与耦联结构的自振频率进行比较，评价了不同力学模型的选取对结果的影响，分析了不同的边界条件对拦污栅框架自振特性的影响，讨论了动水压力附加质量对结构自振特性的影响。研究成果可为工程设计提供理论依据。

| Abstract: | Based on the platform of ABAQUS and ANSYS,the 3D FEM model of single trash rack frame and the coupled model of inlet-trash rack frame and intake of the No.5 generation unit of a hydropower station were established and the dynamic analysis on its dynamic characteristic was conducted.Then the law of main vibration mode shapes was obtained and compared with the results of coupled model.The influence of the selection of different models on the results,the influence of different boundary conditions and additonal... |
