摘　　要：利用最小二乘法和遗传算法,结合实验数据,成功拟合了PP基木塑材料的Cross-WLF黏度模型参数,并加载到Moldflow软件中,对木塑材料的流动性进行了分析。分析说明不能单纯依靠提高注射压力提高木塑材料的流动性,只有当注射压力较低时,效果才明显,分析结果与实验结论取得了较好的一致性。Using the least square method and genetic algorithm , combined with the experimental data, Cross-WLF viscosity model parameters of the PP wood plastic composite materials was successful fitted, and loaded into the Moldflow software, the flow of wood-plastics material were analyzed. Analysis showed that could not rely on the increase of injection pressure to improve the flow of wood plastic material, only when the injection pressure was low, the effect was obvious. The analysis results were well consistented with the experimental results.
