LMS/RLS/OCTAVE Vibration Controls of Cold Orbital Forging Machines for Improving Quality of Forged Vehicle Parts

Cold orbital forging (COF) as an advanced incremental metal-forming technology has been widely used in processing vehicle parts. During the COF process, vibration on machine injures service life of and quality forged part. The study control is therefore necessary. In this study, dynamic model established, performances some key positions are obtained using Matlab&Simulink software. Subsequently, effectively verified by conducting a test experiment. Based dynamics software, least-mean-squares (LMS), recursive least-squares (RLS) OCTAVE vibration-control algorithms applied to reduce vibration. Comparing machine, these useful for reducing which improves effects LMS RLS controls better than OCTAVE, they also obviously machine. first be machines will beneficial future research other mechanical systems.
