Probabilistic Approaches Applied to Excavation Tool Design for Hard Rock Destruction
Original language description
This paper focuses on a numerical analysis of the hard rock (ore) disintegration process. The bit moves into the ore and subsequently disintegrates it. The disintegration (i.e. fracture of the ore) is solved via probabilistic approach (FEM in combinationwith the Simulation-Based Reliability Assessment method - SBRA, i.e. Monte Carlo simulations, stochastic inputs). The ore is disintegrated by deactivating the FE which satisfy the fracture condition. The results are compared with experiments. Application of the SBRA method in this area is a new and innovative trend. Finally, the probabilistic reliability assessment for a new design of a cutting bit (excavation tool) is proposed.
