| Abstract: | Reliability analysis on residual fatigue life of aging platform structures is investigated.The theory of the spectral fatigue analysis was given,the uncertainties in reliability analysis of residual fatigue life of aging platform structures were studied,and a failure function of the residual fatigue life was presented,and sensitivity analysis was performed.Results show that the uncertainties in reliability analysis of residual fatigue life of aging platform structures can be well accounted for in the limit ... |
