| 摘 要： | 在Hele-Shaw近似下,采用有限元和有限差分混合法求解粉末注射成型充填过程,有限元法处理中面离散,厚度方向使用有限差分,运用控制体积法追踪运动边界,压力方程和能量方程顺序求解,实现了复杂型腔不同流率多种浇口下充填过程温度场、压力场和速度场以及运动前沿的数值仿真分析,得到了较有价值的数值实验结果。

| Abstract: | A FEM/FDM method is used to model the powder injection molding under the Hele-Shaw approximation with the control volume method dealing with the moving boundary. The mid-surface is discretized by FEM, and the thickness direction is discretized by finite difference method. The pressure equation and the energy equation are used to solve in sequence. Valuable data can be resulted numerically from the simulation of temperature, pressure and velocity fields. |
