Abstract

The paper aims at the frequency analysis problem of the uncertain structure, takes the space beam structure with interval parameters as the research object. An expression of the relationship between the structural natural frequencies and the interval parameters is presented. With the partial derivative of the frequency in this expression, the frequency sensitivity of interval parameters is obtained. On the basis, a frequency analysis method is presented which built on the discriminant of the sensitivity monotonicity. Use this method, a frequency analysis is carried on a simplified GARTEUR plane model. The method is then verified by using an optimization algorithm. The frequency analysis method presented in this paper has a certain theoretical and practical significance in the dynamic analysis of uncertain structure.
