An approach for the reduction of the steering wheel vibration, occurring at engine idling, is described. The reduction of the vibration can be achieved by increasing the resonant frequency of the steering system, which is constructed of a steering wheel, steering column, its support member and so on. In this paper, an experimental modal analysis to clarify the resonant phenomena and an eigenvalue analysis with FEM to suggest practical hardware modifications are discussed. We have found that the approach introduced here can be applied to conceptual primary design of steering system.
