Abstract:
In response to the challenging issue of titanium alloy wire processing, a finishing process equipment is used for surface turning and finishing processing. To improve the surface processing quality of the finishing equipment, an electromechanical coupling model is established, considering the interaction between the mechanical, electrical, and control systems. The accuracy of the mechanical dynamics model and the electromechanical coupling model is verified through experiments, and vibration characteristics are analyzed under the electromechanical coupling model. The study explores the system's dynamic characteristics under different motor speeds and feed rates, and investigates the impact of changes in mechanical parameters on system vibration. Experimental verification shows that the electromechanical coupling model more accurately reflects the real system characteristics. Vibration characteristics analysis reveals that with changes in motor speed and feed rate, the magnitude and trend of vibration in the cutting system also change. By comparing the error between the theoretical mean of displacement and the experimental value, the appropriate motor speed and feed rate are selected to improve the cutting efficiency and surface machining quality.
