• Resumen

  • This study analyzes and controls the vibration of a vehicle steering wheel by employing the acceleration transfer path analysis (acceleration-TPA) method and vibration sensitivity method. A steering wheel vibration test is conducted to determine the critical engine speed and corresponding frequency. The acceleration-acceleration transfer function from mounts body side to the steering wheel is derived and tested. The acceleration spectrum of the steering wheel is synthesized, and the accuracy of the synthetic results is evaluated. The vibration transmitted by each path is investigated, and the main vibration participation paths are identified. The interaction mechanisms between the path transfer vibration, path vibration participation, and total vibration are further obtained. The critical parameters of the main vibration participation paths are matched, modified, and experimentally verified for vibration control. The results indicate that pertinently matching the stiffness parameters of the mounts and reducing vibration sensitivity of the structure lead to decreased dynamic force transmitted by the paths and controlled steering wheel vibration.
