摘要
采用改进后的Lempel-Z iv的复杂度算法,对构建的结构位移响应符号序列进行复杂度分析.分析结果表明,所构建的振动系统响应符号序列复杂度可以很好地反映结构的固有振动特性.该算法简单、可行,并且不依赖于结构计算模型,为结构振动控制算法提供了一个新的途径.
The eigenvalue of movement response of structure is an important parameter characterizing the system intrinsic characteristic. In order to quantify the information of vibration response, the complexity algorithm proposed by Lempel and Ziv is used to calculate the complexity of symbolized displacement re- sponse sequences. Then from the data result, it shows that using complexity to characterize response can well reflect the vibration characteristic of structure with arithmetic simplicity, and provide a new approach for structure vibration control arithmetic.
