Abstract
A new method for identifying the bushing stiffness parameters in car suspension mechanisms is presented. This method is based on the observation of part motions in a suspension on a kinematic and compliance test bench. This observation is used to compute bushing deflections for various load cases applied on the suspension. An iterative identification method has been set up and interfaced with commercial multi-body simulation software (ADAMS) in order to find a set of stiffness parameters that achieve the correlation between model and reality. This identification method is tested on a pseudo-McPherson suspension and on a complex multilink rear suspension. In each case, the behaviour of the identified model converges towards the reference behaviour.
