Probability Analysys for Rolling Rolls Calculation as per Probabilistic Method

Two calculation methods are mainly implemented during the construction as well as modeling of the rolling rolls. These are: deterministic (classical) and probabilistic – calculation based on reliability. When using deterministic method, starting point considers that the workloads as well as material specifications are invariable values. However, in reality, rolling rolls are burdened with variable workloads. Material quality is variable value as well. This includes the fact that the solidity of materials which are inputted into calculation is also variable value and that these materials have their own points of dissipation. This paper is giving an option of probabilistic method application for calculations with rolling rolls based on their reliability. Proper workloads were analyzed as well as the practical application of the same as well as material solidness variability; this was the base for the calculation method introduction. Therefore, by applying the probability method, we are able to achieve more accurate results because we are incorporating stochastic variability of the calculation elements.
