摘要
通过理论分析和数值仿真,研究了冲击振动落砂机周期运动的稳定性与局部分叉,揭示了冲击振动落砂机周期运动经概周期分叉和倍周期分叉向混沌的演化过程。周期运动的稳定性与分叉研究可以为冲击振动落砂机的动力学优化设计提供理论依据。
Stability and local bifurcation of two kinds of inertial shakers are investigated by theoretical analysis and numerical simulations. It is demonstrated that the system can exhibit chaotic behaviour via Hopf bifurcation or doubling-periodic bifurcation of periodic impact motion. Routes from Hopf bifurcation and doubling-periodic bifurcations of periodic impact motion to chaos are discussed. The system parameters of shaker may be optimized by studying of stability and bifurcation of periodic impact motion of shaker.
