【Abstract】 The die forming process of a hydro turbines blade was simulated by the thermal coupled finite element method. The distribution of stress, strain, temperature and contact area with dies on a workpiece and their variations during the deforming process were obtained, and then compared with experimental results. The results provided a theoretical basis for understanding the deforming mechanism and selecting reasonable parameters for the die forming of a hydro turbine blade.更多还原
