Abstract

This invention discloses a data processing-based method and system for vibration control of cultural relic display cases. The method includes: acquiring vibration signals of the display case at different time periods by deploying sensors, and filtering and time-calibrating the vibration signals; constructing a three-dimensional model of the display case and assigning values ​​based on the material properties of the ground structure; discretizing the three-dimensional model into a finite element mesh; using the calibrated vibration signals as external excitation input to drive the finite element mesh to obtain the vibration propagation path; determining the optimization objective based on the vibration propagation path, and obtaining the optimal parameters of the optimization objective through a genetic algorithm; using these optimal parameters as reference values ​​for vibration control of the display case. This invention, through multi-band vibration signal processing, three-dimensional modeling of the display case, and optimization of the vibration path using a genetic algorithm, achieves dynamic adaptability, precision, and efficiency in vibration control of cultural relic display cases, providing a scientific and effective solution for the protection of cultural relics in complex vibration environments.
