| 摘 要： | 本文通过计算机仿真，观察和研究了Ｍｉｓｅｓ桁架的动力不稳定及其混沌特性．结果表明，对于调和外激励的某一频率和幅值，存在着周期或非周期的特性；而当动力外激励为阶跃函数时，不引起混沌响应．

| Abstract: | The dynamic instability and chaotic behaviours of the well-known Mises Truss are investigated by computer simulation in this paper.The results show that periodic and aperiodic behaviours exist for certain values of the amplitude and frequency of the harmonic excitation.Dynamic loading in the form of a step function does not cause any chaotic response.This study reveals the importance of the chaotic dynamic analysis of structures in addition to their static and dynamic instability analyses. |
