密炼机转子的优化设计

Optimal design of internal mixer rotors

以单位体积胶料的能耗最小及强化胶料在密炼室内轴向循环流动为优化目标 ,对本伯里型密炼机转子的主要几何结构参数进行了优化设计。转子的优化设计属于多维有约束的非线性规划问题。根据数学模型的特点 ,选择复合形法进行寻优。结果表明 ,与同类型机台相比 ,优化效果明显 ,几何参数的最佳取值合理。

The optimal design of the major geometrical parameters for Banbury mixer rotors was conducted taking the aim at minimizing the specific energy consumption of rubber compound and increasing the axial circulating flow of rubber compound in mixer chamber.The results showed that the optimized design was remarkably superior to the conventional design,and the acceptance of geometrical parameters was reasonable.
