| Abstract: | A new approach to calculate safety index of the ICE components is presented. The design point method is applied to reliability problems of ICE components and finite element method and artificial neural network techniques are introduced into this approach. A practical example of calculating safety index of the turbocharger compressor blade is illustrated. It shows that the new approach is feasible and superior and will provide a new way to calculate safety index of the mechanical parts. |
