Abstract: Parameter uncertainty of structural systems is inherent in most engineering problems. It is necessary to study the reliability of uncertain systems. Frequency analysis is important for reliability study of dynamically uncertain structures. In this paper, the criterion is used that the difference between the natural frequency and driving frequency should be less than a specific value. The reliability mode and the safety probability of the random axial vibration systems of rods are defined as a series mode, and the frequency reliability analysis method for avoiding the resonanse is proposed. The quasi-failure analysis method for resonant problem of the random axial vibration systems of rods is studied.
