双向渐近结构拓扑优化 bidirectional evolutionary structural optimization method
结构的宽带随机振动理论是随机振动理论中一个引起兴趣的领域。这种随机振动模态数量很大,从而呈现简单的渐近趋向。
Wide band random vibration of structures is an interesting area in the theory of random vibration in which the number of responding modes is so large that some asymptotic behaviour may be observed.
应用该同步控制方案,可以在驱动系统结构和参数未知及不要求混沌参考信号连续可导的前提下,实现构造响应系统的输出渐近同步于任意标量混沌信号。
The output of the response system is controlled to asymptotically synchronize with any scalar chaotic signal without continuous derivatives of the driver system with unknown structure and parameters.
讨论了一类带有扩散和具有阶段结构与时滞的两种群捕食系统,分析了该系统的非负不变性、边界平衡点性质及全局渐近稳定性。
