该文应用通用Hele－Shaw模型,采用有限元/有限差分方法对GMT充模流动进行模拟,在模拟结果与实验结果相吻合的条件下,研究了合模力、合模速度及模具温度之间的关系,得出在相同模温下,当合模速度为20mm/s时,合模力具有最小值;而在相同合模速度下,模温越高,合模力越小.研究的结果将为工业生产提供一定的理论指导.“,”The GMT compression molding was numerically simulated with generalized Hele-Shaw Model by FEM/FDM by FEM/FDM. After the simulation results were pred to be congruent with the experimental results,the operation variables,such as closing foree,closing speed and mold temperature were studied. The conclusion was that the closing foree will attain a minmum value at the closing speed 20mm/s,and the closing foree will decrease with temperature. This study will Provthe a theoreicai guidance to industrial practice
