查询词典 forced vibration

Furthermore, the non-linear global stiffness matrix is updated in the time domain as the riser deforms.7, Potential relationship between the freely vibration and the forced oscillation has been investigated and a theory model is successfully constructed.

该理论模型可同时考虑到雷诺数和质量阻尼比对横向振幅幅值的影响，同时也再次证明雷诺数是影响涡激振动横向振幅的一个重要参数。

They can be a support for thedesigner to look insight of the vibration mechanism of the mistuned bladed disk, andto predict its forced response. Therefore, the researches of this dissertation canprovide fundamental theories for studying and designing the power systems of thenew high performance aero-engines.

本文的研究结论，不仅在很大程度上完善和发展了研究失谐叶盘系统振动局部化问题的基础理论，也为设计人员正确理解失谐叶盘系统的振动机理及准确预测其振动响应提供了有效的方法和手段：并为进一步研制高性能的叶盘动力系统打下了理论基础。

The objective of the test process was to examine how the signal-path loss varied after exposure to different levels of vibration, and if discontinuities could be forced through long-term fretting wear or by unbiasing the spring contact with excessive shock.

测试的目标是检验在施加不同程度的振动之后，信号路径损失是如何变化的，以及是否会通过长期接触磨损或通过用过度冲击使弹簧不偏置而形成不连续性。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
