  1. Experimental determination of mechanical mobility - measurement using impact excitation with an exciter which is not attached to the structure

    機械機動性實驗測定.第5部分:使用激發器
  2. It is generally very difficult to measure excitation in operating environment in the case of the complexity of the structure or the variant forms of the excitations, sometimes it is even immeasurable for the impact location is usually inaccessible

    由於工程中結構的復雜性及激勵形式的千差萬別，工作狀態下激勵載荷常常難以測量，甚至因載荷作用點的不可達等原因而使實際載荷不可測量。
  3. In this way, the simulation results of hxmt become more reliable. the simulation analysis results of collimator parts indicate that, the collimator parts meet design standard in sine excitation state, but not in impact excitation state or

    這些分析方法的採用，在有限的計算機資源條件下，考慮了更多的結構細節，使得對整體結構的計算結果具有更高的可靠性。
  4. Excitation setting is one of the important control devices for hydraulic turbine generator unit. its performance is a key factor which impact directly on the safety and stability running of the unit itself and power system

    勵磁裝置是水輪發電機組的重要控制設備之一，其性能的優劣直接關繫到機組自身和電力系統的安全穩定運行。
  5. Experimental result shows that electrical - resistance strain gages can respond well in the frequency range of artificial excitation by impact hammer, at the same time, the experimental scheme brought forward in this paper makes the experimental setting simple and can be manipulated easily as well as can display the excitation and response expediently and synchronously on digital oscillograph. the impact hammer can implement half - sine load

    結果表明，電阻應變片在力錘激勵頻段內可以有很好的響應，從而使實驗裝置簡單，方便操作和使用；同時實驗結果顯示出本文採用的實驗方案可以方便地將激勵和響應同步地顯示在示波器上，並且利用力錘可以實現規則的半正弦加載。
  6. Detailed numerical studies are presented for the transitional dynamics of the steady - state motions of those systems with the variation of the excitation and the system parameters, with the illustrations given for rich nonlinear phenomena, such as the bifurcations of periodic vibro - impact motions and the chaotic vibro - impact motions. in chapter 5, the existence of the periodic vibro - impacts, as well as the corresponding stability is analyzed for an oblique - impact vibrating system composed of a spring - pendulum and an oscillator. when the system damping and the tangential friction

    結果表明，在無阻尼、無摩擦的簡化情況下，周期斜碰撞振動運動具有嚴格的存在條件，並隨激勵參數的變化出現復雜的分叉和穩定性的反復切換；運動阻尼可在較大參數范圍內對非穩定運斜碰撞振動系統動力學研究（ 5 ） （ 6 ）動鎮定;相對而言，切向摩擦對系統穩態特徵的影響不大。
