The purpose of this work is to evaluate the effect of the deformability in the compliant joints on the static behavior of the guiding mechanisms used for the independent suspension of the cars’ rear axle. The idea is to comparatively analyze the static behavior of the rigid model (with connections between bodies realized by spherical joints) relative to the real elastic model (with compliant joints - bushings), with the aim to establish if the rigid model assumption is useful for the static analysis. The comparative analysis between the compliant and rigid models is applied considering the general cases of guidance of the rear axle, with mono-mobile (by five points) and bi-mobile (by four points) guiding mechanisms. The study is conducted by using the MBS (Multi-Body Systems) software environment ADAMS.
