Embodiment
[0056] The main implementation process of the present invention for structural damage identification is as follows: figure 1 As shown, the specific steps of a structural damage identification method based on subspace projection and sparse regularization are:
[0057] S1. Acceleration sensors are arranged on the structure to record structural response information;
[0058] S2. Arrange force sensors at the excitation point, and perform test modal analysis on the structure in the non-destructive state (non-destructive structure) and the structure in the damaged state (damaged structure) respectively, and extract the structural modal information;
[0059] S3, select the structural feature quantity and parameters, and establish the sensitivity equation;
[0060] S4. Construct a measurement matrix satisfying the D-RIP condition;
[0061] S5. Perform subspace projection on the sensitivity equation;
[0062] S6, introduce l 1 Norm regularization to establish structural damage iden...
