Experimental Study on the Resonance Fatigue of Stiffened Structures

In order to understand the structural response characteristics of stiffened plate structure which is often used under dynamic load, the stress and strain response of the type structure under the vibration, especially the resonance condition, and the life characteristics of the stress-strain response are analyzed. This paper designs a stiffened plate structure of resonant loading and data acquisition system to accomplish the above objectives. Experiments show that the whole process of the experimental system is relatively stable, operable, and can be able to complete the expected experimental objectives, while provide a strong support to the structural vibration fatigue on the further study.
