【Abstract】 To address the problem of multi-motor system synchronized switching direction process control,this paper studied the reliability and stability of the wire winding system,which directly influenced the stability of roller wire speed and the performance of main axis transmission system.The mathematical model of the transmission system was built,and each essential factor,which influenced the sensitivity and precision of the transmission system,was investigated.Through theoretical analysis and experiment simulation,the transmission effect in trapezoid wire winding curve and the double cosine half-wave speed rule curve was studied.And the wire winding algorithm of single cosine half-wave has been proposed.The simulation and experiment results have proved that the transmission efficiency is high,the velocity curve is smooth and the transition time is short.更多还原
