| Abstract | ||
| This paper, we propose a method for considering uncertainties based on the projection on polynomial chaos. The proposed approach is used to study the nonlinear dynamic response of one stage gear transmission system with uncertainty associated to eccentricity defect and this uncertainty must be considered in the analysis of the dynamic analysis of this system. The simulation results are obtained by the polynomial chaos approach for dynamic analysis under uncertainty. The proposed method is an efficient probabilistic tool for uncertainty propagation. It was found to be an interesting alternative to the parametric studies. The polynomial chaos results are compared with Monte Carlo simulations. | ||
