This paper presents a study on the rotational vibration sensitivity of automotive hydraulic power steering systems. In order to describe non-linear dynamic coupling effects between the steering rack-pinion gearbox and the hydraulic sub-system, we build two different models and co-simulate the mechanical system based on multi-body dynamics and the power system based on the hydraulics. The frequency responses of the steering wheel to the rack force are obtained to compare the experimental results. The agreement between simulation and experimental results shows the validity of the co-simulation model. The sensitivity analysis for the factors, such as rack friction, valve opening area, torsional stiffness and the inertia of the steering wheel are carried out by the design of experimental method. From the factor analysis results the effective methods to reduce the steering wheel vibration are proposed.
