摘　　要：复合挤出机机头是橡胶工业中有不可或缺的一部分,合理的设计挤出机机头流道与橡胶挤出成型质量有着密切的联系。基于此,这里对复合挤出机机头流道进行了分析优化设计。运用FLUENT软件,对复合挤出机机头其中的一个分支流道进行具体的优化分析。首先对阻尼块的高度、深度以及形状进行了结构优化分析设计,其次对分支流道分流区的角度进行了优化分析设计,通过确定阻尼块的形状、高度和深度,改变分流区的角度,降低了流道进出口的压力降,减少了流道的阻力,提高了出口速度的均匀性和产品的质量。The head of compound extruder is an indispensable part of rubber industry.The reasonable design of the flow channel of the head of extruder is closely related to the quality of rubber extrusion.Based on this,it analyzes and optimizes the flow passage of the compound extruder.The FLUENT software was used to optimize the flow channel of a branch of the compound extruder.First on the depth of the height of the damping block,and shape are analyzed in structural optimization design,the second branch of the Angle analysis,the optimization design of flow diversion area,through the determination of damping block shape,height and depth,changing the Angle of shunt area,reduces the flow of import and export pressure drop,reduce the flow resistance,improved the uniformity of the exit velocity and the quality of the products.
