Abstract: To satisfy people-s pursuing for individuality, an assumption of designing a new sport car was presented. Front double-wishbone suspension was designed basing on the whole vehicle-s design parameters and suspension design theories. Suspension-s virtual prototype modeling was built in ADAMS/View. By doing the design study, the assembly angles with horizontal plane of lower control arm and upper control arm were the best influential design variable on each appraisable target of suspension-s performance. These two design variable could change not only the size variation but also the trends. Cut-off point of tie rod influences toe angle greatly impacted wheels toe angle. When consider performance change and variation trend influences, optimization design was done. Lack of cornering and back to performance were ensured. The optimization results meet the demands of suspension design, and show that the suspension performance parameters achieve the ideal variation range, and is the combination of production, experiment and research.
