Reliability Analysis of Ventube Fan Rotor
Journal Title: Problemy Mechatroniki. Uzbrojenie, lotnictwo, inżynieria bezpieczeństwa - Year 2015, Vol 6, Issue 2
Abstract
Discs of ventube fan rotor were chosen as an object of the study. As a result of an analytical calculation, distribution of radial and circumferential stress and safety factor along rotor’s disc radius was calculated. Present paper displays relation between reliability function of structure element and safety factor through introducing probabilistic description of its value. Presented form of the reliability function gave the possibility of influence’s estimation of stress and strength’s variate dispersion round the expected value on reliability of structure element. Authors weighed deterministic value of safety factor against its value calculated in probabilistic way for various stress and strength distribution parameters.
