| The work aims to optimize the structure size of bellows, minimize the stress concentration of bellows, and improve the fatigue life of bellows. The parametric modeling of bellows used in the vacuum interrupter was carried out by using ANSYS Workbench, and the transient dynamics analysis was carried out for the complex working conditions of coupling speed and external pressure. A single-objective optimization design of key geometrical parameters of bellows was carried out with the aid of DOE (Design of Experiment) technology, and the optimization results were checked for strength and fatigue life calculation. The results show that the optimization results meet the design requirements. The maximum equivalent stress of bellows is reduced by 28.8% and the fatigue life is increased from 3 064 cycles to 32 260 cycles while meeting the strength of bellows under complex conditions of coupling velocity and external pressure. The optimized structure effectively reduces the stress concentration in the dangerous parts of bellows, and the fatigue life is improved. |
