Abstract

A model is developed for analyzing the fundamental static and dynamic performance of a power steering. The basic inertia, stiffness and damping properties of each component are taken into consideration. A dynamic friction model is introduced for precise modeling of the losses of the gear meshes, the yoke support and the bearings. The torque ripple generated by the universal joints of the intermediate shaft is considered. The assist motor (brushed DC type) and its power electronics are represented in a 4-quadrant model. Static and dynamic responses of this power steering model are validated against experimental data.
