摘　　要：针对陶瓷练泥机挤出的泥料表面和内部存在问题,在陶瓷练泥机的挤出螺旋铰刀轴上添加由压电陶瓷产生的轴向超声振动,实现练泥机挤泥过程中减粘降阻的效果。通过分析泥料运动机理,使用SolidWorks软件建立泥料三维模型,最后将建好的三维模型导入COMSOL有限元分析软件进行仿真分析。结果表明:对陶瓷练泥机的挤出螺旋铰刀轴施加轴向超声振动能够降低陶瓷泥料与铰刀及轴面之间的黏附阻力,减小泥料的平均速度梯度,提高平均速度。在振频为24 kHz、振幅为0.6 mm时,挤出泥料平均速度梯度降低37.42%,平均速度提高至0.0161 m/s,减粘降阻效果较为明显。Aiming at the problems on the surface and inside of the clay extruded from the ceramic clay trainer,this paper adds the axial ultrasonic vibration generated by piezoelectric ceramics to the extruding screw reamer shaft of the ceramic clay trainer to realize the effect of viscosity and resistance reduction in the process of extruding clay by the machine.By analyzing the motion mechanism of the clay,we use SolidWorks software to establish a three-dimensional model of the clay,and then contuct a simulation analysis of the three-dimensional model after being put in COMSOL finite element analysis software.The results show that applying axial ultrasonic vibration to the extrusion screw reamer shaft of the ceramic clay trainer can reduce the adhesion resistance between the ceramic clay and the reamer and the shaft surface,reduce the average velocity gradient of the clay,and increase the average velocity.When the vibration frequency is 24 kHz and the amplitude is 0.6 mm,the average velocity gradient of the extruded clay is reduced by 37.42%,and the average velocity is increased to 0.0161 m/s,which is a fairly obvious effect of viscosity and resistance reduction.
