Stochastic model and reliability assesment applied for platinum ore desintegration process
Original language description
This paper focuses on a numerical analysis of the hard rock (ore) disintegration process. The bit moves into the ore (i.e. mechanical contact with friction) and subsequently disintegrates it. The disintegration (i.e. stress-strain relationship, reactionforces and fracture of the ore etc.) is solved via the FEM in combination with SBRA (Simulation-Based Reliability Assessment) Method. The ore is disintegrated by deactivating the FE which satisfy the fracture condition. Material of the ore (i.e. yield stress, fracture limit, etc.), is given by stochastic inputs. The results are compared with experiments.

Pravděpodobnostní model a určení spolehlivosti aplikované na desintegraci platinové rudy
Czech description
Příspěvek je zaměřen na numerickou analýzu dezintegrace platinové rudy. Dezintegrace platinové rudy je řešena metodou konečných prvků v kombinaci s metodou SBRA. Materiál, jimž je ruda tvořena je popsán pomocí náhodných vstupních veličin. Výsledky výpočtu jsou porovnány s výsledkem experimentů.
