Abstract:In view of the problem that the current theoretical model of a flat balloon limits the rapid development of spinning speed of ring spinning frame，a mathematical equation model of yarn winding radius and traveler turning radius changing with time is established by considering the effects of air resistance and the Coriolis inertial force is proposed.By studying the twisting and winding process and the forming law of bobbin yarn，the relationship between the rotation speed of traveler and spinning speed and spindle speed is obtained.According to the principle of torque balance，the formula of torque balance of traveler is established，and the variation law of three spatial inclination angles of traveler is obtained.Based on the image processing and analysis technology，the image feature points are extracted and analyzed，and the theoretical model is optimized according to the analysis results.It is pointed out that the mathematical model can accurately predict the variation law of the camber angle and camber angle with time，and lay a theoretical foundation for the rapid development of the spinning speed of ring spinning frame.It is of great significance to improve the spinning quality of ring spinning，reduce the breaking rate of spinning，and design and use the system of ring and traveler.
Key Words:traveler；force analysis；air resistance；Coriolis inertial force；image processing；motion model
