| 摘 要： | 阿海水电站人工砂石系统筛分楼动力计算，是在静力设计所选定结构截面的基础上，按照结构动力学的计算方法，计算支承结构的固有振动频率及筛分机周期性振动力作用下的动位移，要求支承结构不发生共振，控制动位移值在允许范围之内，并核算主要支承结构的动内力和疲劳强度。一般情况下，若筛梁及主梁满足最大动位移控制条件，则动弯矩和疲劳强度可自动满足。简要介绍了筛分楼支承结构的简化动力计算方法，其计算结果与实际运行情况基本一致，能够满足目前水利水电工程中的砂石加工系统筛分楼的设计要求。

| Abstract: | Based on the structural section determined by statics calculation,the dynamic calculation for screen tower of artificial aggregate system of A'hai Hydropower Station is implemented according to structural dynamics,including the natural vibration frequency and dynamic displacement,for preventing resonance of the structure and controlling the dynamic displacement in a allowed range,moreover the dynamic stress and fatigue strength of the main supporting structure is checked.Under a normal condition,the dynamic... |
