Abstract
As the core component of the modern industrial equipment, the dynamic performance of the mechanical transmission system directly affects the operation efficiency and stability of the equipment. In order to solve the problem of both accuracy and real-time performance under complex working conditions, this paper proposes a dynamic performance improvement method of mechanical transmission system based on multi-ob jective cooperative optimization. With the goal of improving the response speed of the transmission system and reducing the vibration and noise, combined with finite element analysis and intelligent algorithm, a dynamic characteristic model including key parameters such as stiffness, damping and mass distribution is constructed. By introducing the adaptive weight adjustment mechanism, the precise regulation of the system performance under different working conditions is realized, and the effectiveness of the method is verified by experiments. The results show that this method can significantly reduce the vibration amplitude in the range of system resonance frequency, and improve the transmission efficiency by about 15%.
