Abstract
When performing three-dimensional braiding, the carrier base of a conventional braiding machine can only be move on a single track, but cannot be switched between tracks. In this study, a three-dimensional braiding machine with orbital change interlocking is designed to realize the carrier track change. Aiming at the crucial components in track change interlocking mechanism, the track change process is separated into seven periods, and the driving function of slider and electric rotary are obtained. The kinematics model of track change interlocking mechanism is established, the velocity, position and trajectory of carrier base are analyzed on ADAMS simulation software. The results show that the carrier base maximum velocity is −226.51 mm/s, the carrier base maximum position is 68.30 mm, and the carrier base maximum vibration is 0.14 to 1.08 mm in track change process, prototype test indicate that three-dimensional braiding machine with track change interlocking is feasible, provides reference for the future design of three-dimensional braiding machine.
