| 摘 要： | 分析了梁摆系统的耦合振动,梁和摆均考虑为线性.研究发现该系统含有非线性动力行为,在某些条件下会发生叉形分叉.用结构动力学理论建立了梁摆系统的耦合振动方程,用摄动法求出了系统的近似解,分析了该系统的动力响应及分叉.最后用MATHMATIC软件对分叉点前后动力响应进行分析.

| Abstract: | The dynamical characteristics for the coupled pendulum and beam system were studied.The nonlinear characteristics,including geometrically nonlinear and physically nonlinear,were not considered in the beam and pendulum.But the nonlinear items were found in the coupled vibration equations derived from structure dynamics.Using the perturbation method,the dynamical response and bifurcation were studied.Using the software MATHMATIC,the responses of point near the bifurcation point were obtained. |
