| Abstract: | Numerical analysis and experimental investigation were carried out to study the strength and low cycle fatigue life of the BLISK with carbon fiber reinforced plastics(CFRP) ring.Firstly,based on the mechanical behavior analysis and properties test of CFRP,the numerical analysis on the stress-strain,vibration modal and LCF life of the BLISK with CFRP ring were presented.Secondly,strain measure,modal test and LCF spin test were performed successfully.Finally,the comparison of the numerical results with the experimental data shows good consistency. |
| Keywords: | Blisk structure Carbon fiber reinforced plastics Strength Fatigue life |
