C-L Method and Its Application to Engineering Nonlinear Dynamical Problems
-
摘要: C-L方法可以揭示非线性振动系统的分岔特性,它结合对称性和奇异性理论并将Liapunov-Schmidt(简称LS)约化方法推广到非自治系统.作为应用实例,分析了非线性转子动力学低频振动分岔失稳问题的机理及其控制.Abstract: The C-L method was generalized from Liapunov-Schmidt reduction method, combined with theory of singularities, for study of non-autonomous dynamical systems to obtain the typical bifurcating response curves in the system parameter spaces. This method has been used, as an example, to analyze the engineering nonlinear dynamical problems by obtaining the bifurcation programs and response curves which are useful in developing techniques of control to subharmonic instability of large rotating machinery.
