Estimating System and method of modal parameter for real-time monitoring of structures

摘要

The present invention relates to a system and method for estimating a structure dynamics for real-time structure monitoring, including a target frequency setting unit for measuring a response of a structure and setting a target frequency, a filter for filtering a response of a structure, A modal response unit; a mode shape carving unit for calculating a model with the obtained pseudo-modal response and generating a mode shape piece changing with time; and a mode correlation coefficient calculating unit for calculating a mode correlation coefficient from the generated mode shape piece And a mode shape estimating unit for estimating a mode shape of the structure from the calculated mode correlation coefficient.
