| 中文摘要: |
| 从理论和实验两个方面对橡胶注射过程的温度分布进行了初步研究。温度场的离散曲线可根据稳态导热微分方程求得。温度用数理分析法、有限元法和流变法计算结果相差不大：数理分析法＜有限元法＜流变法。最佳硫化时间可根据硫化程度公式计算,当α≥0.9时，硫化时间为最佳。实验测试了橡胶注射机加热板、喷嘴和胶板的温度分布，实验值普遍大于理论值，平均偏差约为2.5 ℃，相对误差为1. 6%。 |

| A preliminary investigation was made theoretically and experimentally on the temperature profile in rubber injection moulding.The scatlergram of temperature field was obtained based on the differential equntion for stabe heat conductivity.The temperature calculated with mathematic statistical method showed little difference from those calculated with finite element method or rhe,)logical method. The optimum cure time was calculated with the equation.when α≥O.9.The temperature profile on the heating plate,injection nozzle and rubber slab was measured. In general,the measured value was higher than the calculated one. The average error was about 2.5 ℃ and the relative error was about 1.6%. |
