Dynamic Response of Dual-Disk Rotor System with Uncertainties Based on Chebyshev Convex Method

In this paper, a non-probabilistic Chebyshev convex method (CCM) for the transient dynamics of dual-disk rotor system with uncertain parameters is proposed. The dynamic equation derived by finite element (FEM), and deterministic response obtained. Then CCM used to obtain responses system. amplitude ranges characteristics are quite close calculation results Monte Carlo simulation (CMCS), which verifies accuracy validity CCM. experimental demonstrate that proposed has good performance in uncertainty analysis More importantly, will be helpful understand behavior systems uncertainties provide guidance robust design analysis.
