The aerothermoelastic analysis of missile structure includes the thermal stiffness, thermal vibration and thermal flutter analysis. this dissertation emphasizes on thermal vibration analysis of the aerial vehicle under aerodynamic heat condition
本文研究背景是彈體這類典型結構在高速飛行情況下，由於氣動加熱引起的高溫對結構氣動熱彈性分析，包括熱剛度、熱振動問題的研究。It showed that activated inhibition by weak noise could be gabaergic inhibition. from above the findings, we could give a hypothesis that the input of random oscillation induced by noise in the cochlea to central auditory system could be integrated in the central auditory nucleus and the response of sound - sensitive neuron to sound stimuli could be adjusted to an optimum state for signal intensity coding
根據這些變化可以推測，這種背景噪聲的生物學作用可能是通過弱噪聲所引起的耳蝸隨機共振的輸入，在上行過程中經各級聽覺核團的整合，將中樞聲敏感神經元調定在一種準備狀態，並定型放電率函數和調制神經元對聲馨碩士學位論文master 』 st砰iesis強的編碼。In this thesis, a multi - disk rotor supported by two plain journal bearings is used for the numerical and experimental studies. the one aim is to analyze the nonlinear dynamic characteristics of the rotor system under different varying parameters ; the methods of online elimination of the oil whip and subharmonic vibration are developed and studied also. besides the expression of the nonlinear oil film force is proposed, so that the unbalance of the nonlinear rotor system may be identified online
作者在總結了前人大量的有關非線性振動研究工作的基礎上，確立了本文的研究目標：一是以工程應用為背景，研究轉子-軸承系統由非線性油膜力引起的非線性振動特性以及各種影響因素，力圖通過對轉子-軸承系統非線性振動特性的分析，找到切實可行的在線消除油膜振蕩的辦法；二是研究非線性油膜力的表達方法式，使非線性轉子系統的不平衡量在線識別成為可能。Rolling bearing ’ s vibration signal has a strong background yawp, the different fault cause the different characteristic of vibration. particularly the scathing fault, will not only cause the low frequency impact vibration, but also rise the high frequency inherence attenuation vibration of the bearing
滾動軸承振動信號具有背景噪聲強、不同故障引起不同特徵振動的特點。尤其是損傷類故障，不但會引起低頻沖擊振動，還會激起軸承系統的高頻固有衰減振動。After summing up the background component in these two items, the background and resonant components of wind - induced response and eswl can be decided. the modal solution is applied to obtain the wind - induced response and eswl on beams supporting roofs
將非交叉項的貢獻分為背景分量和共振分量，將交叉項的貢獻確定為背景分量，從而將模態交叉項和非交叉項的貢獻與背景分量、共振分量確立起對應的關系。Stochastic resonance is a new and very important embranchment in the nonlinear academic domain. it is a very important new thought of combining sr theory and dsp technology together to form a faint signal detecting system, which is used in weak signal detection under strong background
隨機共振是目前非線性學術領域的一個新興的重要的分支，而把隨機共振理論和dsp技術結合起來形成強噪聲背景下的小信號檢測系統並應用到實際工程信號的檢測中去則是本文的一個創新點。分享友人
