摘　　要：利用显示动力有限元法对U_(10)Mo/Al弥散燃料板的轧制过程进行模拟,研究了热轧工艺参数对弥散燃料板芯体轧制变形和接触压力的影响。有限元模拟计算结果表明:轧制速度对燃料板芯体的应变速率有明显影响;轧制过程中燃料板芯体所受的表面接触应力和变形均随压下率的增加而增加;随着摩擦系数的增加,芯体宽展率逐渐降低,而其表面接触压力相应增加。With the explicit dynamic finite element method, the rolling process of U10Mo/Al dispersion-type fuel plate was simulated, and the effect of rolling processing parameter on the rolling behavior and contact pressure of fuel plate was investigated. Finite element simulation results show that the rolling speed is with obvious effect on the strain rate of fuel meat. The deformation and stress condition of fuel meat would be increased with the increasing of the reduction rate. As the friction factor increasing, the spread rate reduces gradually, but the stress on fuel meat grows accordingly.
