摘要 用ANSYS有限元软件对生产宽幅橡胶板材的螺杆分配机头流道内部的压力场进行三维模拟与分析 ,选择Fluid 14 2三维六面体单元划分网格 ,建立螺杆分配机头内部流道的三维有限元模型 ,得到在一定工艺条件下机头流道内部的压力分布。分析了阻尼块几何形状对压力分布的影响 ,指出阻尼块可以增加流道内原来速度和压力较高部位的流动阻力 ,选择合适的阻尼块高度可以使胶料的压力值逐渐趋于横向均匀。 The 3D simulation and analysis of the pressure distribution in the flow channel of the screw die for producing wide rubber sheet were made with ANSYS FEA software.A 3D model of the flow channel in the screw die was established by selecting the network devided with Fluid 1423D hexahexahedron units to obtain the pressure profile in the flow channel of screw die under certain working conditions.The effect of the geometry of damping block on the pressure distribution was analysed.It was found that the flow resistance at the places in the flow channel,where the speed and pressure were higher,could be increased by the damping block;and the pressure of extruded compound became more uniform in the lateral direction by selecting the proper height of damping block.
