| 为了探究粉体喂料3D打印机输送螺杆的构型对打印制品表面质量的影响，课题组使用三维软件SolidWorks绘制出3种螺槽深度分别为
1.8,1.8~3.7和3.7 mm的输送螺杆；采用有限元分析软件ANSYS对3种螺杆分别进行模态分析和谐响应分析，得到3种螺杆的各阶固有频率和坐标轴上的响应频率。对
比研究表明螺槽深度为1.8~3.7 mm的螺杆的力学性能更好。最后经过实验打印金属制品，比较使用各螺杆打印制品的表面质量，验证了有限元分析的准确性。该
研究为螺杆构型的优化设计提供了一种新方法。 |

| In order to analyze the influence of the configuration of the power feed 3D conveyer screw on the surface quality of printed products, 3D software
SolidWorks was used to draw 3 kinds of conveying screws with depth of 1.8, 1.8～3.7 and 3.7 mm respectively. Modal analysis and harmonic response analysis of 3 kinds of screws
were carried out by the finite element analysis software ANSYS. The natural frequencies of 3 kinds of screws and the response frequencies on the coordinate axis were obtained.
Comparative studies show that the mechanical properties of the screw with the depth of 1.8～3.7 mm were better. Finally, the surface quality of the experimentally printed products is
compared with each other to verify the accuracy of the finite element analysis, which provides a new method for the optimization design of the screw configuration. |
