- Abstract:
- The auricle fracture failure occurred in a gas vessel vibration experiment is analyzed in this paper. The hypostasis reason of the vessel structure failure was disclosed in the viewpoint of structure dynamics. An improvement idea is offered for the initial failure. Several modified models are proposed according to the idea and the actual products. The effects of different modified models were contrasted through structure dynamics simulation. Accordingly the optimal modified model was ascertained. The modified vessel structure was verified by random vibration test. The test result shows that the stress on the auricles of the modified vessel is obviously reduced in the process of the vibration, and the improvement measure is effectual and feasible in avoiding the structure fatigue failure.
