In the fourth chapter, the oscillation of a nonlinear beam under the axial harmonic force and the bifurcation of the weak or strongly nonlinear system have been studied
第四章討論了一個受軸向簡諧激勵作用下的非線性梁的運動，運用傳統的galerkin法得出時域上的動力系統，再對該系統弱、強非線性情況下的分叉進行了研究。 -
The method of change partial differential equation into ordinary differential equation is classified, the bifurcation and chaos in nonlinear schrodinger system is detected and the effectiveness of controlling chaos of buckling beam with parametric perturbation method is studied in details. chapter 7 is the summary and conclusion of the dissertation
第六章總結歸納了將非線性偏微分方程轉化為常微分方程的變換法，研究了一維無界區域上非線性薛定諤方程的分岔和混沌性質，解析地研究了用參數周期擾動法控制屈曲梁的混沌運動的效果。 -
Abstract : in this paper, the feature of time - bifurcation for plate - beam stability is studied by mechanics model of plate - beam structure of rock in compression. the instability time of plate - beam is dependent on the rock material feature. delay bulking occurs under some load. the formula of time - bifurcation is given. the mechanisms of roadway floor heave and delay rockburst are preliminarity discussed
文摘:採用巖石板裂梁的縱向受壓的力學模型，考慮深部巖石的流變性，分析了板梁穩定性的時間分叉特性.板梁失穩與巖體的流變性質密切相關，在一定載荷下，經歷一段時間后會發生延遲失穩，給出了時間分叉點的計算式.並對深部礦井延遲性巖爆發生機制進行了初步分析
