The Modal Analysis of the Main Steel Structure of Bucket Wheel Stacker Reclaimer

The vibration mode of main steel structure of bucket wheel stacker reclaimer is complex and changeable, so its modal analysis is necessary. In this paper, the main steel structure of bucket wheel stacker reclaimer was integrally designed and its main parameters were determined. then the finite element model of the main steel structure of the bucket wheel stacker reclaimer was established and the modal analysis was simulated, finally the results of its inherent frequency were calculated by FEA method.
