Abstract: This paper presents the design and experimental validation of an explicit parametric model for mono tube dampers. The aim is to develop a model with few physical parameters, in order to make it both easy to manage and computationally light. Firstly, the model is validated with the help of a dynamometer. In addition, advanced experimental work has been developed, which makes the model match the desired results in an acceptable manner during real driving manoeuvres with a single seater sports car on a track. A good correlation has been achieved in real time, so it allows us to have a good feeling about its further use as a subroutine on full model simulations or on semi-active suspension control systems. This paper describes custom built experimental tools and techniques used to validate the model as well as results illustrated on the figures presented.

Keywords: mono tube dampers; parametric models; damper models; fast explicit models; experimental tools; model validation; track testing.
