| 摘 要： | 研究了激励点位置对于梁、板结构输入功率的影响规律。研究表明:在不改变结构参数和激励特性的情况下,对于激励位置的优化不仅可以减小结构的振动能级,而且能抑制结构共振时的响应特性。由此提出了控制结构振动的新途径,激励点的位置对于结构的振动特性有着不可忽视的影响,并具有广阔的应用前景。

| Abstract: | This paper studies the influence rule of exciting position on power flow input of girder and plate structure.The study shows that the optimization of exciting position without change of structure parameter and exciting feature can not only decrease the vibration energy level but also eliminate the feature of structure resonance time.Therefore,a new method has been put forward.Exciting position has inevitable effect on structure vibration,and has wide application in future. |
