实体上的流动分析

传统的应用“中面模型”技术的2．5维方法在预测薄壁制件成型过程中的流动行为是非常成功的，但“中面模型”在应用过程中是非常不方便的．通过使用实体表面作为流动平面，在厚度方向上添加虚拟热流道来保持熔体在实体表面一致地向前充填，并比较了模拟结果与Han的实验结果及摩托车后视镜的缺料注射结果．算例分析表明，这种方法对实体充填模拟是有效的．

Flow Analysis on Solid Geometry

Conventional 2.5D analysis technology which adopts the "mid_plane model" has been successful in predicting filling behavior for most plastic parts,especially for the thin shell parts.This imported model causes some inconvenience during its application.This study introduces surface model as the datum plane,instead of the conventional mid-plane model and additional hot runner elements in the gapwise direction are employed to keep the flows in the surfaces at the same section coordinative. The simulations presented here are compared with the available data from Han and the short-shot experiments for rearview shell.It proves to be feasible for flow simulation on solid model in injection molding.
