| 中文摘要: |
| 对橡胶注射过程中的压力变化进行了理论与实验研究。充模流动模型的压力、能量控制方程为：?/?x（J?P/?x）+?/?y（J?P/?y）=F·ρCP（?T/?t+U?T/?x+V?T/?y）=k?2T/?z2+ηγ2。选用高斯方法求解总体有限元方程。实验与计算分析对比证明，本文选用的数学模型和计算方法所得结果与实测结果基本吻合。该模型可用以代替大量的实验，对橡胶充模过程进行模拟，并用Grapher软件对数值结果进行处理，以图表直观地表达出各种因素对充模过程的影响。 |

| An investigation was made theoretically and experimentally on the pressure variaion in rubber injection moulding.The pressure and energy control equations in the filling flow model，were as follows：?/?x（J?P/?x）+?/?y（J?P/?y）=F·ρCP（?T/?t+U?T/?x+V?T/?y）=k?2T/?z2+ηγ2.The Gaussian method was used to solve the general finite element equation.It was showed through the Comparative analysis that the results obtained with the selected mathematical model and calculation method were approximate to the measured ones.The proposed model could be used instead of a large number of tests to simulate the rubber filling process.The resultant values were treated with Grapher software.The influence of various factors on the filling process was expressed directly by figures and tables. |
