Research of Sensor Optimization Algorithm for Vibration Monitoring of Crane Structure

Abstract:

Safety requirements for large crane become more and more rigorous, as the crane is widely used in various fields. The health monitoring technology of cranes can provide early warning and the location of damage for a long time. It has great significance that people can monitor the crane operation in real time. Thronging establishing three-dimensional simulation model, an optimization algorithm on sensor used in crane structure is introduced in this paper, which is based on algorithm of QR decomposition and Modal Assurance Criterion. Character of structure in space is considered in research. The modals of displacement were chosen on the foundation of structure vibration characteristics in different direction, so that sensor layout could not be affected by vibration characteristics of simplified modal. Under the guidance of optimization algorithm selected above, the research shows that sensor layout would be affected by optimization algorithm and modals of displacement. By choosing Structure mode shape which can reflect the real structure, study indicates that well project of sensor layout can be well provided on the basis of algorithm of QR decomposition and Modal Assurance Criterion.
