Abstract
This contribution encompasses the sensitivity analysis of flexible rotor with active vibration control subjected to uncertainties. The uncertain parameters consist of small variations that are modeled by using random variables and random fields. The structure response subjected to uncertain parameters is analyzed based on the stochastic modeling. Numerical simulations illustrate the structural response of the rotor and their sensitivity indices.
Highlights
Smart rotors are flexible rotors that include a control system to reduce the vibration
Eleven uncertain parameters are considered in this contribution, ES, kx1, kz1, kx2, kz2, cx1, cz1, cx2, cz2
The time domain analysis of the rotor with uncertain parameters was computed by considering a rotation speed of 1600 RPM in which the rotor operates above its first two critical speeds
Summary
Smart rotors are flexible rotors that include a control system to reduce the vibration. Several methods have been used to analyze effects of the uncertainties in the structural response of flexible rotors: stochastic finite element method [6], fuzzy dynamic analysis [7], fuzzy-stochastic dynamic analysis [1] and polynomial chaos theory [8] among others. In this contribution, a smart flexible rotor under random uncertainties parameters is analyzed. The sensitivity regarding the orbits is examined by using the global-based sensitivity method
