SIMULATION AND ANALYSIS OF SHEET MOLDING COMPOUND COMPRESSION MOLDING FLOW

摘要

摘要: 本文采用有限元分步计算方法,对酚醛片状模塑料(P-SMC)在模压过程中的流动变形情况进行了计算机仿真模拟,与试验结果做了对比。编制了相应的有限元计算与后处理软件,分析了模压料在封闭模具中充满模腔的过程、在一定合模速率下的充模时间以及在一定粘度下的模压成型压力。对SMC模压时模具的设计以及优化成型工艺参数具有一定的理论指导意义。

Abstract: Automatic computer simulation of phenolic sheet molding compound(P-SMC) compression-mol ding flow is realized by finite element step-by-step computing method, and compared with the result of experiments. Finite element computing and postanalysis programs have been written. The compr ession mold filling process, time and pressure needed of PSMC in a closed mold are analyzed. It will be of theoretical significance to mold design and to the optimization of the techno logical parameters in the compression molding of sheet molding compound.
