[Abstract]:Quayside container crane (quayside crane) is the core equipment of port and wharf operation. It is necessary to carry out real-time monitoring and fault warning of the shore bridge. The crane management system (CMS (Crane Management System) is a monitoring system installed on the shore bridge, which can monitor and display the fault information in real time. But at present, the CMS system can not monitor the stress state of each part of the steel structure of the bank bridge. As a key component of shore bridge operation, steel wire rope is prone to fatigue fracture, once it breaks, it will lead to a huge disaster. Based on the above considerations, this paper studies the on-line visualization of the stress of the quayside container crane based on the field CMS system information and the method of predicting the residual fatigue life of the wire rope according to the steel wire life. Firstly, the stress analysis method of the steel structure and wire rope under different working conditions is studied. The finite element model of the steel structure and wire rope of the quayside bridge is established, and the stress distribution of the steel structure and the wire rope of the shore bridge under different working conditions is analyzed, and the results of stress analysis are obtained, which provide support for the subsequent work. Secondly, the fatigue life of wire rope is analyzed on the basis of the stress analysis of wire rope, and the method of analyzing the fatigue life of wire rope is put forward according to the relationship between the number of wire rope broken and the fatigue life of wire rope. Based on the theoretical calculation, the S-N curve of steel wire rope is obtained, and the load spectrum file of wire rope is obtained by combining with the dynamic acceleration measurement during hoisting process. The fatigue life of wire rope is analyzed in Workbench, and the fatigue life value of steel wire is calculated. The fatigue life of wire rope is obtained by reanalysis. Thirdly, the method of on-line stress calculation and visualization is studied. Based on the running data of CMS system, the simulation of virtual bank bridge system and real shore bridge system is realized. The stress values of the steel structure at the present time are calculated by interpolation in real time during the operation process and are mapped to color for dynamic display. Finally, based on the above work foundation, the on-line visualization simulation system of quayside container crane operation and stress is developed, which can display the stress state of the steel structure and wire rope of the quayside bridge in real time. The number of working boxes and the number of remaining working boxes of wire rope are displayed in real time to predict the remaining life of wire rope. The system is helpful for the maintenance staff to see directly the stress changes of each part during the operation, especially the stress in the key position, which can provide auxiliary information for the establishment of the operation and maintenance scheme of the shore bridge.
