Structure Analysis of FBD No8.0/2×55kW Local Counter-Rotating Fan Impeller
In order to further explore the possible optimization path of the local counter-rotating fan impeller structure,this paper takes the FBD No8.0/2×55 kW counter-rotating fan as the research object,conducts mechanical analysis and modal analysis of the fan impeller through three-dimensional modeling and finite element analysis,and determines the direction of the impeller structure improvement according to the analysis results.Then NACA4415 airfoil blade is used to optimize the impeller structure.The results show that the stress and strain of the optimized impeller blade are significantly reduced,and the risk of resonance is also greatly reduced,indicating that this analysis and optimization work has certain practical significance,and can provide reference for subsequent research.
