Multibody dynamics modelling and system identification of a quarter-car test rig with MacPherson strut suspension

In this paper, the authors develop a multibody dynamics model of a quarter-car test-rig equipped with a MacPherson strut suspension and they apply a system identification technique on it. Constrained equations of motion in the Lagrange multiplier form are derived and employed to characterise the dynamic behaviour of the test rig modelled once as a linear system and once as a non-linear system. The system of differential algebraic equations is integrated using a Hilber–Hughes–Taylor integrator. The responses of both models (linear and non-linear) to a given displacement input are obtained and compared with the experimental response recorded using the physical quarter-car test rig equipped with a MacPherson strut suspension. The system identification is performed for control purposes. The results, as well as the performance and area of applicability of the test rig models derived, are discussed.
