摘要
Abstract
The fatigue life analysis of high-pressure cylinder under sinusoidal vibration based on the Miner linear damage accumulation theory was carried out.The high-pressure cylinder finite element analysis (FEA)model is established with the bracket and corrected by the experimental data.The evaluation method of fatigue life based on the damage accumulation theory is proposed.With the stress-frequency da-ta obtained from the FEA and the proposed method,the fatigue life of the key structure of the cylinder is evaluated.The fatigue life evaluation can provide useful reference for the structure design.关键词
