The fan blades macroscopic fracture morphology linzhang mine fan blade fracture location are located at the root of the blade arc transition, fatigue source area is located in the blades and hub transition acute angle side of the center line of the source location is located away from the fan blade width small end near the 1/3 position, line source. From Figure 1, can be observed a # blade fatigue fracture extension area was penetrating crack growth, fracture rougher edge area of ??Huanghua mine fan parameters, expand the relatively small ridge Cixian metal mine fans, and also the location of fatigue crack initiation Visible secondary cracks. 2 # blade fatigue fracture extension area is relatively small, but the extension is more coarse ridge. Finite element analysis model object of this study is a single-stage axial fan for coal mine ventilation, for the geometry of the axial fan, establishing its rotor system, and passed the theoretical vibrational frequencies obtained by the Riccati matrix method to secondary reliability card processing finite element method. Methods fan rotor vibration characteristics of the entire system for the fan rotor vibration characteristics estimated reference.
