A method, system and storage medium for structural monitoring and evaluation of complete inverse analysis

Abstract

The invention discloses a complete inverse analysis structure monitoring and evaluation method, system, and a storage medium. In the scheme, monitoring modes of unit indexes and structure indexes areconstructed, fixed parameter values necessary for a calculation process of a corresponding mode are determined, and each monitoring mode is used as the minimum unit of a calculation unit and the structure indexes; then, the signal amount collected under the constructed monitoring mode is acquired, the collected signal amount is converted to a corresponding measurement physical amount, and the measurement physical amount is then converted to a corresponding direct physical amount; and finally, the corresponding process physical amount, the unit indexes and the structure indexes are obtained based on the obtained measurement physical amount and the direct physical amount by using the constructed monitoring mode and serve as direct evaluation objects for the structures and the components. According to the scheme, the structural safety and the use performance are reversely deduced completely through monitoring data, and the whole process does not depend on finite element calculation results of a design structure.

Description

technical field [0001] The invention relates to a structure monitoring and evaluation technology, in particular to a structure monitoring and evaluation technology based on complete inverse analysis. Background technique [0002] Structural monitoring and evaluation mainly includes two parts: data monitoring and structural evaluation. Data monitoring mainly solves the selection, installation and combination of instruments and equipment, the filtering and noise reduction of original signals, and the data processing of the physical transformation process. Structural evaluation mainly solves the problem of measuring the measured physical quantities (such as strain, inclination, temperature, directional displacement, etc.) that can be identified by engineers through a series of inverse calculation methods at the component and structural levels to obtain the safety and performance of components and structures calculation evaluation results.

Problems solved by technology

[0008] Through the analysis, it can be seen that the scope of application of the existing evaluation schemes is limited, and they are all calculation methods for specific monitoring data proposed in a specific environment. The limitations are all based on theoretical calculation results for monitoring auxiliary calculation and correction methods. The core is still dependent on the structural finite element forward calculation results. A number of design constraints are added to the processing of structural monitoring data, which reduces the validity and effectiveness of monitoring data. reliability
