摘要: An analytical procedure is presented to find approximately the nonlinear normal modes in conservative two-degree-of-freedom system by using principle of least action and assuming that modal curve straight. The results are compared with those numerical experiments utilizing 4th order Runge-Kutta method, it found there good agreements between them. By this procedure, demnostrated compute which analytically extended from linearized generically or non-generically bifurcated do not have any counterpart linear theory.
