Behavior Diagnostics of Bucket Wheel Support Structure Using Finite Elements Method: Optimization of Structures

Abstract:

Most common types of bucket wheels were analyzed by finite elements method in this paper. Also, relevant diagnostics parameters are defined for various constructions (stress concentration, deformation energy, distribution of potential and kinetic energy for main oscillation shapes). This approach enabled identification of weak spots and selection of such types of bucket wheel which are most suitable for specific working conditions on open cast mine.
