自然激励下建筑结构的模态参数识别，首先通过自然激励技术（next）得到结构的自由响应，然后由自回归滑动平均（arma）方法识别模态参数。-natural incentive structures under the modal parameter identification, First through natural incentive Technology (next) to be free to respond to the structure, then autoregressive

先对数据进行ARMA建模，再在ARMA建模的基础上进行Kalman滤波已经运行通过，而且效果很好-ARMA modeling data first, and then on the basis of ARMA modeling performed by the Kalman filter has been running, and the effect is very good
