摘　　要：采用Deform软件对生物质复合材料连续固态挤出自增强过程进行计算机模拟,通过对速度分布云图以及最大等效应力场的分析,研究了挤出口模锥角对连续固态挤出自增强过程的影响;同时,通过实验对挤出过程中制品的表面形态与模拟结果进行对比,验证了模拟结果的可靠性,最终发现选取口模锥角20°~30°可以获得理想的生物质复合材料制品。The simulation was done on the self-reinforced process of continuous solid-state extrusion for biomass composites using Deform software. Through the analysis of the velocity distribution and curve of max equivalent stress, the influence of different die angle on the self-reinforced process of continuous solid-state extrusion could be got. At the same time, the comparison of product surface by experiment was done with the result of simulation so as to verify that the simulation was reliable. At last,the conclusion that the die angle between 20° to 30° was suitable to get the ideal biomass composite product.
