摘要
利用点映射-胞映射法(简称PCMAS)分析了分段线性-非线性振动机械的周期运动关于激振角频率ω的分叉情况,同时对 P-2 运动的稳定性进行了深入的研究,所得结论对于设计这类机械有指导意义.
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.
