摘要
讨论了拉伸速度呈周期变化的受拉非线性弹性直杆的动力行为· 采用Melnikov方法研究时发现 ,材料的非线性使得动力响应发生异常 ,对确定的直杆而言 ,当拉伸速度超过某个临界值时 ,动力系统将出现次谐分岔和混沌·
The dynamics behavior of tension bar with periodic tension velocity was presented. Melinkov method was used to study the dynamic system. The results show that material nonlinear may result in anomalous dynamics response. The subharmonic bifurcation and chaos may occur in the determined system when the tension velocity exceeds the critical value.
