六自由度3D打印机平台的设计与分析

Design and Analysis of 6-DOF 3D Printer Platform

近年来,机器人学的发展打破了传统3D打印机打印位置的局限。多自由度的运动模式有更灵活的打印轨迹和更丰富的机构设计。本研究以基于Stewart并联机构的3D打印机械结构为研究对象,确定了并联机构的具体尺寸,对3D打印机主体框架进行结构设计,利用Solidworks建立机构平台的三维模型,并分析其运动轨迹,将模型导入Matlab软件进行运动学仿真分析,运用Ansys进行静力学分析。本研究可以在材料承载端提供六自由度的运动,为后续开发多自由度的打印机提供参考。

In recent years,the advances in robotics have broken the limitations of printing position for the traditional 3D printers.The motion mode with multiple degrees of freedom has more flexible printing track and richer mechanism design.Taking the 3D printing mechanical structure based on Stewart parallel mechanism as the research object,the specific size of the parallel mechanism was determined,the structure of the main frame of the 3D printer was designed,the 3D model of the mechanism platform was established with Solidworks,and its motion trajectory was analyzed.The model was imported into Matlab for kinematics simulation analysis,and Ansys was used for statics analysis.This study can provide six degrees of freedom motion at the material bearing end,providing a reference for the subsequent development of multi-degrees of freedom printers.
