Abstract: Dynamic analyses of steering systems were carried out for a certain type of vehicles, and experimental studies were carried out. Vibration responses of the steering systems were measured by transient excitations, and the frequency response function curves of accelerations were obtained. Constraint modal parameters of steering wheels, steering column assembly and tube beam of cross car beam were obtained by hammering method. Modal vibration mode and dynamic stiffness of mounting point were combined into an integrated analysis, and the structure that needed to be optimized was determined. Effectiveness of the optimization scheme was verified by the vibration sensitivity tests of control points of the steering wheels.

Key words: steering system, dynamic stiffness analysis, constrained modal test, steering wheel vibration
