Abstract


Wind turbines ( referred to as a fan ) spindle is one of the main components of the wind turbine , pay close attention to the context of the development of wind energy , wind turbine spindle manufacturing has a huge market in worldwide countries . As the core component of the large - scale wind turbines , to withstand the torque spindle high performance requirements . With the development of wind resources , increasing fan spindle size , shape and production tools are extremely special , especially in the forging process , process requirements , need water pressure overload forging production difficult , so its forging posed new challenges for the forming process . For the current the fan spindle complex process and the problem of excessive equipment tonnage requirements , existing water pressure on the development of the new the fan spindle forging process were prepared performance , safe and reliable operation of the fan spindle imperative . On the basis of the traditional craft a new rotating the fan spindle of forging process and designed a new fan spindle forging tooling , new tooling forging forging stock , both to avoid the equipment tonnage restrictions , but also ensure the forging forming effect forming quality . In this paper, the numerical simulation of three-dimensional rigid viscoplastic thermal coupling finite element numerical simulation software DEFORM - 3D the fan spindle rotation forging process . Analysis of metal flow law the fan spindle rotation forging process , blank internal equivalent strain distribution and forging the required load . In addition to forming the factors affecting the in-depth study and proposed solutions . Eventually each analysis object forging effect assessment index , preferably of the fan spindle rotation forging process parameters and to determine the optimal parameters of the forging process .
