forced vibration method meaning in Chinese
强制振动法
Examples
- The result of the experiment shows that the proposed forced vibration method device has the quality of stability and repetitiveness of the data , the wide range of the testable reduced velocity , the exactness of coupled and direct flutter derivatives . and it does not need to employ any complicated identification system to check it further
结果显示：本文提出的强迫振动法装置具有试验数据稳定、数据重复性好、可测量的折减风速范围宽、交叉项导数与对角项导数具有同等精度和不需要复杂的系统识别过程等一系列优点。 - As to the current problems existing in the identification for these flutter derivatives , the dissertation tries to trace the development in the identification for the past unsteady aerodynamic forces of long - span bridges . it also investigates the method for flutter and buffeting analysis and the flutter derivatives . based on the present methods used in obtaining the unsteady aerodynamic forces and flutter derivatives , and co - funded by a natural scientific fund from the nation and a key project fund from the railway ministry , the current research has attempted to develop a device which can be employed in the wind tunnel to test flutter derivative through a forced vibration method
鉴于目前桥梁断面颤振导数识别的水平和存在的问题，本文通过对大跨度桥梁非定常气动力、颤振分析方法及颤振导数识别方法的回顾和评述，基于现有的非定常气动力和颤振导数的测试方法，在国家自然科学基金与铁道部重点学科基金的联合资助下，研究开发了一套在风洞中采用强迫振动法测试颤振导数的装置。
