| Abstract: | Bifurcations of period motions on the self-excitation frequencies in nonlinear vibration mechanism with piece-wise linearity are analyzed by means of the point-mapping and cell-mapping synthetic method. Stability of P-2 motion is investigated as well. Some conclusions are helpful to design this kind of machines. |
