Abstract: Aiming at the deficiency of the research on the motion of the yarn carrier of the rotary threedimensional braiding machine,the dynamic study of the rotary threedimensional braiding machine was carried out,the simplified three dimensional model of the threedimensional braiding machine was established by the software of SolidWorks, and then which was imported into ADAMS. The kinematic pair and the drive were added to the simplified model, the reasonable simulation parameters were set,and the dynamic simulation analysis was carried out.By means of changing the radius of the track and the angular velocity of the angle guide wheel,the regularity of velocity of the yarn carrier was obtained under different radius of the orbit or different angular velocity. And the correctness of the simulation analysis was verified through the experiment study.The results indicate that the velocity curve of yarn carrier has a periodicity, the product of the period and the angular velocity is approximately 2π. At the transition,the velocity reaches the peak, and there is a large contact impact,which lays the foundation for the followup orbit optimization of the rotary threedimensional braiding machine.
