Theoretical and experimental vibration analyses of the steering wheel of a heavy commercial vehicle

In this study, the components of a particular heavy commercial truck that affect the steering wheel vibration are identified and the most common sources of this vibration are examined. Then, modal analyses and impact hammer tests are implemented to determine the root causes of the vibration. Finally, finite element modeling is applied, and all the results of the analyses are compared to present design improvement recommendations for the reduction in steering wheel vibration, which can be applicable in new projects.
