【Abstract】 During the design of an axial flow fan, the cascade design of the moving blade has been finished. In order to improve the security of the blade, the failure analysis of the blade has been finished with the finite element method. The simulation results show that the failure position is near to the root of the blade where the inner stress is the concentrative. The method above can improve the dependability of the design, and has important value of engineering applications.更多还原
