中文摘要:
      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。
英文摘要:
      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.
