摘　　要：为实现某新型PBX捏合机的温度分区控制目的,采用有限元模拟软件ProCAST对其传热效果进行仿真模拟研究,探索其控温系统结构对PBX平衡温度分布的影响。结果表明:初始结构下捏合机的恒温控制结构及分布不合理,造成中间腔室内的平衡温度分布不均匀,温度较较低,温差较大;改进后的捏合机中间腔室内的温度接近理想温度,平衡温度分布均匀,过渡区温度梯度大,梯度方向垂直于中心水平线,整个捏合机在水平方向上的温度能实现从50℃到60℃再到50℃的温度分区。In order to achieve the temperature zoning of certain type PBX kneader,the heat transfer effect of the kneader and the influence of temperature control system structure on the equilibrium temperature distribution of PBX is explored by finite element simulation software ProCAST.Result shows that the temperature control structure and distribution of kneader under the initial structure are irrational,resulting in low temperature,large temperature difference and uneven distribution of equilibrium temperature in the middle chamber.After the improvement,the equilibrium temperature is close to the ideal value with uniform distribution in the middle chamber of kneader.The temperature gradient in the transition zone becomes large,and the gradient direction is perpendicular to the central horizontal line,thus achieve the temperature zoning from 50℃to 60℃and then to 50℃in the horizontal direction.
