Abstract

In this paper, free vibration of a rotating beam is studied. Cross sectional area, elasticity modulus, moment of inertia, shear modulus, density and rotational speed are modeled as random variables. To study uncertainty, the stochastic [mite element method and second order perturbation technique are applied. The effects of rotational speed, setting angle and random property variances on "Coefficient of Variation" of first mode eigenvalue are investigated. This analysis is carried out for the Timoshenko and Bernoulli-Euler beam theories. Also, to determine the significance of random properties on response variation, a sensitivity analysis is applied. Results show that the first eigenvalue sensitivity curves for Bernoulli-Euler and Timoshenko beam models are approximately identical.
