Study on Dynamic Load Identification of Max-phase System Based on the Inversion System Method

在目前的载荷识别研究中,有关时域内载荷识别在其逆传系统的载荷识别研究一般只停留在最小相位系统上.本文在时间序列模型的逆传系统动态载荷理论基础上,提出了最大相位系统动态载荷识别新方法,克服了传统识别方法对边界条件的限制,并利用计算机仿真验证了该方法对最大相位系统的载荷识别的有效性.

At present,the study of the inversion system method of load identification in time domain was only limited to that of minimum phase inversion system.Based on time series model for dynamic load identification study,a new method based on inversion system method was proposed for max-phase system dynamic load identification.This paper offered a new method to solve the problem of traditional load identification method that the boundary condition of structure was only applicable to minimum phase inversed systems.Through computer simulations,it was demonstrated to be the effective method for the load identification of max-phase system.
