Abstract：

Based on finite element analysis software,the cold rolling process of certain alloy blade was simulated.The influences of friction factor and rolling speed of rollers on the equivalent stress and spread of blade were systematically studied, and the condition of metal flow was analyzed.The model of cold rolling die was established by software of UG NX6.0, and the roller and blade were respectively treated as rigid body and elastic-plastic material. Based on the explicit dynamics module of finite element software, the forming process of cold rolling was accomplished. The simulation results show that the maximum equivalent stress value on the blade surface increases with the increment of friction factor and rolling speed, but the increasing amplitude is limited. From the root to top of blade, the spread value of blade increases gradually, and finally reaches a stable value. The spread of blade firstly increases and then decreases with the exaltation of rolling speed. There is little influence of friction factor on the spread of blade.The changing law of blade spread after simulation agrees well with the measurement one.
