摘　　要：利用ANSYS热分析模块,得到圆柱形橡胶厚制品在传统工艺条件下的温度变化过程,并绘出制品不同位置胶料的硫化效应曲线。根据橡胶材料的硫化条件,计算得到其最小硫化效应及最大硫化效应,结果发现传统工艺条件下的制品在内层达到最小硫化效应时外层严重过硫。改变工艺条件,通过APDL参数化语言设计,实现由5级硫化温度与9级硫化加热时间组成的45组不同工艺条件的循环分析、结果存储及自动筛选,得到硫化质量满足要求且效率相对较高的工艺组别。结果表明,采用APDL参数化语言,进行数值模拟分析,能够实现橡胶厚制品硫化工艺条件的优化设计。Using ANSYS heat analysis module,the temperature changing process of cylindrical thick rubber products under traditional process conditions and the curing curves in different position were obtained.According to the curing condition of rubber materials,the maximal and minimal cure were calculated. The results showed that,under traditional conditions,the outer layer was seriously over cured while the inner layer reached minimal cure. With APDL parametric design language,the cycle analysis,data storage and screening of 45 groups of different process conditions consisting of five temperature levels and nine heating time levels were achieved,and the groups giving good curing quality and high efficiency were found. The results demonstrated that the curing process of thick rubber products could be optimized by numerical simulation with APDL parametric design language.
