Abstract
Bucket Wheel excavators play a very important role in handling ore material in mining sites. These machines possess many structural and mechanical components that work regularly under stringent operating conditions. The development of more precise and accurate procedures to predict the mechanical behavior of mining machine components and to provide technical data for more efficient maintenance programs is crucial for large mining companies. This work deals with a numerical analysis based on the finite element method devised to identify the critical components of mining machines that must be monitored during their operating cycles. Continuous monitoring systems provide technical data about the mechanical condition of component, leading to more precise estimates of operational parameters, useful life, and damage detection. The procedure implemented in this work is capable of predict the stress and strain levels of the mechanical and structural parts of Bucket Wheel Excavators under heavy loads, allowing the selection of the locations for measuring the mechanical response of the system and mounting the associated transducers. The finite element model can generate strain and vibration data to help selecting the monitoring variables and to specify and configure the sensors used in the monitoring system. The experimental data collected from the predicted critical points of the machine are analyzed to produce indicators of the machine condition, which can be used to detect potential failures, improve the maintenance plans, and to estimate the remaining useful life of components.
