Abstract

Turbine disk is a key component of aero-engine and the failure of turbine disk will lead to disastrous consequences, making the structural reliability analysis for the turbine disk as an urgent issue. Taking the turbine disk as the case study, this paper will compare two non-probabilistic structural reliability analysis methods of imprecise structural reliability analysis and interval structural reliability analysis aiming at providing a more profound understanding about the theoretical system of imprecise probability theory. Moreover, according to the comparisons, this paper will predict the prospects or the works should to be done for the widely application of imprecise probability theory.
