摘要: Purpose – The purpose of this paper is to perform experiments on a full scale turbine blade attached part actual disc at elevated temperature, which can accurately predict the life fir‐tree contact under high cycle fatigue (HCF)/low (LCF) combined loading. Moreover, effect shot‐peening lives attachments investigated experimentally by comparing those unpeened ones.Design/methodology/approach An experimental system for temperature established in paper, with new HCF/LCF loading scheme and design clamp. method achieves noninterfering treatment low placing exerting point back mortise. Then tests were performed six used components investigate compared with...
