Abstract
The outer space environment is complex, so the research and development of 3D printing equipment depends on the prototype test that is difficult to achieve on the ground, therefore, the performance of the equipment must be investigated by means of simulation. In this paper, the electro-mechanical joint simulation model of the outer space 3D printing equipment is established based on ADAMS and MATLAB/Simulink, which taking into account the overall micro-gravity environment, the nonlinear friction characteristics of each motion-axis, the inertia of each axis, and the overall frame vibration. Based on this model, the point-to-point control and the interpolation motion errors of X and Y axes with external disturbance is realized. At last the comparative control of motion error is realized, which provides a basis for the development of 3D printing equipment in outer space environment.
