| Abstract: | In order to comprehensively analyze the advantage and structure strengthen problems of fiber reinforcement bling /blisk, the rotor strength optimization and manufacturing requirements were defined. Based on the analysis of mechanical characteristics for typical and special fiber reinforcement bling/blisk, some structure strength design problems such as weight loss, life, strength, stiffness, heat distortion inconformity were proposed by ANSYS, and their mechanisms of problems were studied. It provides reference for structure design, manufacture, testing and examination of fiber reinforcement |
