摘要
以颗粒模型理论为基础对粉末微注射成型二维矩形模腔填充过程进行模拟和分析,证明此方法是可行的,发现了粉末微注射成型的流动主要呈现环状波形效应,波形中心颗粒存在较大的挤压接触力,流动前沿的颗粒则较好地保留在界面前沿,未发生大的侧向位移。
The process of micro powder injection molding for 2D rectangle cavity was studied based on granular model. This approach is proved feasible. The waveform effect is presented in flow of micro powder injection molding. There is relatively great contact force in center of the waveform. The frontal granular is held on the interface front and has no large lateral displacement.
