Synthesis of a rectilinear independent rear suspension and experiment research

This paper synthesises a rectilinear independent rear suspension in order to minimise the variation range of the alignment parameters during jounce and rebound. Simulation through the software of ADAMS verifies the rectilinear motion characteristics of the suspension. Based on the structure design and prototype test of the suspension system, the comparing experiments of rectilinear suspension and MacPherson suspension are carried out with kinematic and compliance (K&C) test rig. The experiments indicate that the alignment parameters of the rectilinear suspension are almost invariable compared with the MacPherson suspension.
