Abstract: In the present paper, the modelling and simulation of a mechanical rack-and-pinion steering gear are presented. The study is performed using multibody simulations that include a reverse geometry rack to predict the functional measurements of the gear. A novel test for the characterisation of the functional performances of a mechanical steering gear is introduced and experimental data are used to validate prediction models.

Keywords: steering system; rack-and-pinion; multibody modelling; functional reverse.
