摘　　要：针对目前3D打印机打印回转体类型零件速度慢、插补复杂、效率低等缺陷,设计一种3D打印机,由底座、行星齿轮组、Z轴运动机构、横向丝杠机构和料架等组成。通过ADAMS仿真软件进行运动学虚拟仿真分析。3D打印机可通过增加打印喷头数量来提高打印速度。通过对多喷头的协作打印方案进行运动仿真模拟计算,得到运动学特性。通过对比分析不同时刻的末端执行器的速度、加速度和受力情况,验证3D打印机机械机构运动可行性。相比于传统3D打印机,该打印机对于回转体零件的打印效率显著提高。Aiming at the defects of slow speed,complex interpolation and low efficiency in printing rotary parts of existing 3D printers,a 3D printer is designed,which is composed of base,planetary gear set,Z-axis motion mechanism,transverse screw mechanism,material rack and so on.The virtual simulation analysis of kinematics is carried out by ADAMS simulation software.3D printers can increase the printing speed by increasing the number of printer nozzles.Through the motion simulation calculation of the cooperative printing scheme with multiple nozzles,the kinematic characteristics are obtained.Through the comparative analysis of the speed,acceleration and force of the end-effector at different times,the results verify the motion feasibility of the mechanical mechanism of the 3D printer.Compared with the traditional 3D printer,this printer can significantly improve the printing efficiency of rotary parts.
