激发频率
激振频率
Examples
- The method can be applied when the size of hull grillage beam and exciting frequencies cannot be easily changed
该法适用于船体板架尺寸、激励频率不易改变的调频情况。 - Under the same conditions , the reflective peak of pile toe in time domain in the former is smaller than in the latter and decreases gradually with the increase of exciting frequencies
研究表明，长径比越小，两者区别越显著，同样条件下，前者的时域底反峰值小于后者，且对激振频率有依赖性，频率越高，底反峰值越小，而后者不能反映这一现象。 - Base on review of existed study and application in suppressing cable vibration in the world , technique of mitigating cable vibration with viscous damper and mr damper has been investigated in this dissertation , and the main contents and progresses in form of summary are as following : 1 the motion differential equations of the cable - damper system are formatted , which take into account these factors , such as the inclined angle , sag , stiffness etc . coupling motion between cable and deck is studied with analytical and numerical method . numerical results show that large amplitude vibration of cable with beat rhythm will occur when exciting frequency of deck equals two times modal frequency of cable
本文在对国内外斜拉索振动控制研究与应用现状进行综合评述、分析的基础上，针对上述问题进行了深入研究，具体的研究内容和取得的成果包括： 1 、建立了斜拉索-阻尼器系统运动方程，对拉索与桥面的耦合振动作了分析和研究，数值结果显示当桥面激振频率等于某阶拉索模态频率的两倍时，很小的初始扰动将引起拉索的大幅振动，并呈现拍振的特征，与实测的拍振信号一致。 - In this paper , the formulas of dynamic parameters provide good method to determine the dynamic parameters , which can reflect the influence of many factors such as the property of soil , the base area of foundation , the pressure of foundation , the exciting frequency and so on
本文得到的地基刚度、参振土质量和动力影响深度的计算公式能较好地反映地基土体性质、基底面积、基底压力和扰频等诸多因素对它们的影响，为更准确地确定机器基础系统的动力参数提供了一种较好的途径。
