| 摘 要： | 考虑材料的粘性和非线性弹性性质，研究了板条在随动载荷作用下的混沌运动，建立了相应的非线性动力方程，利用Melnikov函数给出发生混沌运动的临界条件，结合Poincare映射、相平面轨迹及时程曲线判定系统是否处于混沌状态，并对通向混沌的道路进行了讨论。

| Abstract: | The chaotic motion of a follower forced panel is studied.A nonlinear dynamic equation is derived, with the effect of nonlinear viscoelasticity taken into account. By means of the Garlerkin approach and the Melnikov function method, the critical condition for chaotic motion is obtained. A demonstrative example is discussed through the Poincare mapping, phase portrait and time history. Finally the route to chaotic motion is also discussed. |
