SOLVING SELF-EXCITED VIBRATION PROBLEMS VIA A SELF-ADAPTIVE PRECISE ALGORITHM IN TIME DOMAIN

An application of a self-adaptive precise algorithm in time domain is presented in this paper for solving self-excited vibration problems. By expanding variables at discretized time intervals, a recursive and self-adaptive computation can be conducted. There is no requirement of additional assumption and iteration for non-linear analysis. A couple of examples with high computing accuracy are given to show that the algorithm is a useful tool solving self-excited vibration problems.
