Experimental Analysis for the Steering Wheel Vibration Using Mechanical Impedance Methods 870971

An experimental method for the reduction of the steering wheel vibration, occurring at high speed cruising and/or 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. Mechanical impedance methods were applied to predict the resonant frequency by means of converting the diametrical moment of inertia of the steering wheel into an equivalent mass. This method provides an insight into how design should be changed to obtain further reduction of the steering wheel vibration. Practical applications are also discussed.
