Analysis of Operation Characteristics of FBD No8.0/2×55kW Fan in Coal Mining Face
In order to further explore the possible optimization measures for the fan of coal mine heading face,this paper takes the FBD No8.0/2×55kW counterrotating fan as the research object.Through simulation modeling and finite element analysis,the main mechanism of high deformation,resonance and noise of blade tip under the original scheme is clarified.Then NACA4415 blade airfoil is used as the optimization scheme to optimize the fan.The results show that the optimized blade airfoil plays a prominent role in reducing the deformation and vorticity of the flow field,and also effectively solves the resonance problem in theory,which has potential application value.
