Afterwards , a duffing system with delayed displacement feedback is studied by the method of multiple scales and other numerical methods . the uniform formulas for computing the critical values of time delay are given and the global diagrams of bifurcation for the periodic solutions with respect to the time delay are obtained under different parametric combinations . it is shown that the hopf bifurcation and the saddle - node bifurcation are the only two types of bifurcation observed in such a system
接下來用多尺度法及數(shù)值方法研究了一具有時滯位移反饋的duffing系統(tǒng)的動力學(xué)，得到了不同參數(shù)下系統(tǒng)平衡點發(fā)生穩(wěn)定性切換時的臨界時滯計算公式及關(guān)于時滯的大范圍hopf分叉圖，并發(fā)現(xiàn)saddle - node分叉及hopf分叉是系統(tǒng)出現(xiàn)周期運動的兩個主要的來源。
